2002 Pontiac Grand Prix GTP 60,000 mi,
My ponitac is cutting off driving the road and after about 10min will start. Then you drive it about 15 more miles and it does the same thing. It does not show you a thing going wrong, has plenty of gas and this has happen 4 times since. It has had a fuel pump and sensor put on it at 45,000 and has been in the shop for this before.

Car begins to idle irratically and then will stall after I have been driving it for 20 minutes and it is warm to hot outside. Mostly happens when at a stoplight. So far will start up right away.
Car will starts but dies after 2 or 3 seconds. I've already replaced both fuel pump relays and fuel pump resistor. Car usually cranks and run fine after I let cool down a few hours later.

Stalling ALL the time , every single start, unless giving it almost full throttle fuel.. had to drive it home popping into neutral to restart it over and over again!!!

While driving down the road my car will shut off, I lose everything when this happens. After about 10 mins, will start up & go. Hasn't been fixed. They don't know why it does it.

My 2000 GTP starts up and dies out 2 to 3 seconds later.
The car was cutting off while driving it. It won't restart except after 90 minutes or so. I took it to a shop and they advised me to take it to the dealership because the spark plugs were black and "massive oil leak" was noticeable.... However, I also asked the shop to discard some oil because they had put a little too much oil when the car had had an oil change about a month ago. Researching the internet, I decided to unplug the Mass Air Flow Sensor, as advised in one forum. The car ran perfectly fine with the sensor unplugged. I've just replaced it this morning. No more cutting off. Just a little rough idle probably because the car needs a little time to get adjusted to the new $145 sensor from Pep Boys?
