Just in case this may help someone else: My car (2000, 996, cab with 165,000 miles) quit cold on 3 separate occasions recently. First on interstate at 60 mph; second in stop/go traffic; third while idling in a parking lot. On each occasion, attempts to re-start were useless. Starter turned, motor cranked over, but no firing. After each wrecker ordeal, it always started just fine several hours later. I was clueless. I even had the (original) fuel pump and associated relays replaced on spec. I had to find the cause as I had to be able to trust my car to get to work at all times of the day and night. After third episode, I took it to a local shop (Gold Crest in Kennesaw, GA) They discovered the crank position sensor wire had a hidden break (inside the intact insulation) that would change position and lose continuity when sufficiently heated. Without the signal from this wire, the engine simply would not run. Later, after the car sat for a while, the wire would regain contact, and the engine would start as if nothing ever happened.
