I purchased my Cayman just about a month ago. As I was driving down an entry ramp about two weeks ago I lfted off the gas to slow down and the engine immediately shut off. All the warning lights came on and I turned off the ignition and then restarted the motor and things were fine. Just yesterday, I was pulling out of a parking lot into traffic, again lifted off the gas and the motor shut down just like it had in the previous week. Again it restarted right away but not until I had to drift back into the parking lot and restart. Has anyone experienced this and, if so, is there a fix? Thanks.
this is the first instance of this that I've heard on the board in almost two years (the cars were in the hands of folks in Europe before it was in the US), and the fix in my mind would be a trip to the dealer - pronto. This could be dangerous (as if I have to tell you) and you should have it looked at very soon, I think.

I don't know exactly how the 987 is set up, but when this started happening in my GTI it was due to the throttle linkage coming loose. Maybe there's an idler in the picture? In any case beez has it exactly right, get thee to a dealer stat.
A couple of questions; your car is not in the registry so tell us about it (and add it to the registry). Is it manual or tip, CS or 2.7? Was the car in gear and what gear when this happened? Did you have the clutch (if manual) engaged?
I would think that you should be able, no matter what is causing this, to immediately turn the ignition all the way off and restart the car without having to drift to a stop.
JeffD,
Agree with Beez. Does the check engine light come on and flash yellow? Red? If so, you should take your car in if you can get there at all. Same thing happened to me about three weeks ago at midnight on a Saturday night. Let off the throttle and kills. Check engine light comes on. Engine runs rough. Limped home using handbrake for stops and lights. Called Roadside Assistance and shipped off to New Orleans. Diagnosis: Camshaft actuating element/adjuster leaking internally. Was told by Porsche of New Orleans that my CS was the only Cayman seen with this problem but that they had a Turbo in for the same difficulty. Go figure. Took 3 weeks to resolve and return to me. Runs great again but disconcerting when it happens. I have 4000 miles on my car. Hope this helps.

Wow, I had exactly same problem yesterday night. I called Roadside Assistance and the car towed to Downtown L.A. Motors.
I went to the dealer this morning, and they gave me a Corolla without power windows .

No throttle linkage on the Cayman - or any Porsche anymore.. it's all e-gas - basically a potentiometer, or electronic volume control, if you will... the computer reads the position - sends the gas...

Had a similar experience with a BMW and it turned out to be the ignition switch. Same experience where the engine would shut off unexpectedly, and I also was on an offramp with little place to hide. Good luck.
Interesting. Just happened to me yesterday. I took my bike to a bicycle ride in which a lot of cyclists participated. I stopped (after a 60 mile drive to the ride start) to wait my turn to be told where to park my car. The engine simply cut off making a really strange sound. Never happened before. I tried to start it and it took several attempts. Sounded initially as if it was not going to start. I then parked the car and did the ride. When I got back in the car several hours later, it was fine. Someone did tell me that a rear light does not work at all.
I will call the dealer tomorrrow about both issues.
I have exactly the same problem, got my CS 3 weeks ago. It has happened 3 times already. I've released throttle coming out of 1st gear stepped on the clutch and to neutral, moments later (while clutching) the engine shuts off.
I'll take it to the dealer this week. My worry is that its a problem not easy to reproduce, it has happened in randomly. Dealers usually dont pay attention when THEY dont see the problem

I had a similar problem just today. After almost trouble free driving for over a year a strange thing happened. Had been for a 30min drive, parked the car for about 5mins. Tried to start her up and no go. Tried about 6 times and nothing. Sort of a cough splutter wirr and that was it. Then waited for about 2 mins and had another go. It worked
Werid. I suspect it was lack of fuel feeding, even though the tank was almost full.
So that makes it about 4 random faults so far and all cleared by themselves.
1. ABS and PSM failure. Self fixed 20mins later.
2. Clutch enage position late and random hard grabs. OK 2 days later.
3. No engine start. Ok 2 mins later
4. Sound system died - locked up. Fixed by pulling power fuse.
Hmmmm
PSM - Porsche Stability Management
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility.
The engine can also shut off if you brake whilst pressing the accelerator pedal. I've heard this from more than one person but not experienced it myself so i'm just passing on what i've heard.
Apparently, the engine management system will not allow you to brake and accelerate at the same time.
I've experienced the same thing only once at about km 5000 (now km 23,000). I was slowing down to make a right turn, engaged the clutch to down shift then the car went dead. Restarted and drove away. Just before the incident I saw a group of people staring at my car, so I thought maybe it was just a bad eye effect!
