'02 C 2. 56K mi. Had been driving approximately 15-20 minutes city and freeway. Engine inexplicably stalled and stopped. Pushed around corner to get off busy street, engine restarted easily and quickly, drove about 15 minutes to destination, city driving, no problem. 6 hours later car started easily, and ran normally for about 10 minutes, then stalled again twice. Each time car started easily, ran normally until stalling. Restarted and drove 1/2 mile to fill fuel tank, the computer said I had about 60 mile range. Drove home about 10 minutes away freeway driving, with one stall after exiting freeway, and made it home uneventfully. The issue acted like an electrical problem in my estimation because there was no coughing, or sputtering I associate with fuel starving. Outside temps were 85-90 [hot for Seattle]. No fault codes, just warning lights when engine stalls occurred. Next day drove car about 45 minutes, city and freeway, no issues. 3rd day went to friends who had a OBD II reader with no codes detected.[not Porsche specific reader] Also drove for about 30-40 minutes with no issues. Outside temps were 70-75 degree the last two days, much cooler. Obviously need help. Thanks

Did it stall only when the engine was idling? Any strange electrical issues?

No, normal speed, but before last stall after freeway driving, I heard a slight ticking sound on the freeway.

any recent work done on the car ?

My WAG is a fuel pump is going bad or there's a flaky fuel pump relay.

I could possibly offer up an ignition switch problem but only if you have about a pound of keys hanging on a keychain connected to the Porsche key.

That the behavior appears to be "fixed" (at least temporarily) by turning off the ignition kind of wants me to favor the relay rather than the fuel pump.

I had this identical issue and it was ***BAD NEWS*** [at least for me] all the way- the thrust bearing came out and was found in my oil pan. This meant the crank shaft was running on my block and resulted in a new engine.

However, YMMV, check the crank shaft sensor before leaping to the far gone conclusion that happened to me.

Crank shaft sensor replacement is not that difficult to remove and replace.

Good Luck.

Hello any interested,
Two hours of tech labor for diagnosis, resolution, plus $22 for a fuel pump relay and all is well with precious!

Awesome! Thanks for posting the resolution.
