Engine has cutoff on 3 occurrences: (1) operating the vehicle on the freeway at 70 mph and experienced immediate loss of power. I was able to manuever the vehicle to the shoulder while coasting without engine power. I was able to start the engine but it cutoff a few seconds after. The vehicle had to be towed to an independent Porsche repair shop where the high pressure fuel pump was replaced. (2) the engine cutoff while operating on city street at 40 mph. I was able to manuever the vehicle while coasting without power or power steering into a parking lot. The engine would start but cutoff a few seconds later on multiple attempts. The vehicle has to be towed to the same independent Porsche repair shop where the high pressure fuel sensor was replaced. This occurrence was the first time operating the vehicle after returning home from the high pressure fuel pump replacement service. (3) operating the vehicle while stopped at an intersection at a red light. When attempting to accelerate the engine cutoff and I was stalled for about 1 minute blocking traffic. I was able to restart the engine after a few attempts and drive the vehicle the remaining 2 miles home without incident. All 3 occurences involved abrupt engine cutoff and loss of power steering. The Porsche independent repair shop is unable to pinpoint the issue. The risk exposure to accident is high when engine cutoff occurs while the vehicle is in motion.

There is a strong odor of fuel coming from the driver's rear wheel well. A recall exists for 03-06 models, but my 08 is suffering the from the same issue.

The high pressure fuel pump, car drove with very little ability to speed up. It sputters when trying to accelerate. It won't start right away, building up fuel pressure. I was driving and it just became unresponsive to the gas peddle. I slowed and stopped, restarted and just had a very weak car. It takes some time to reach 50mph. Dangerous if on the hwy.
