Question about Pontiac Grand Prix

01 Grand Prix GTP shut off while driving

I was driving on the highway around 55-65mph and the car shut off like I turned the key, except the oil and check engine light stayed on. No noises, no weird feeling, just shut down. I pulled over, and started it right back up, then drove about 30 miles without any problems. I realize it could be a number of things, but I'm leaning more towards a sensor going bad? Anyone give me at least my best starting point to trouble shoot this? (133k miles, believe it's got a pretty new fuel pump as well.)

Possible CKP sensor. Try to have codes pulled first, a local Checker or Autozone can retrieve them for you.

SOURCE: Car stalled and won't start again

Sounds like it might be either the fuel filter or the fuel pump, cause if you ran the tank down, you probably had sludge in the bottom of the tank that you sucked into the engine, you can try using a fuel system cleaner, you may have sucked sludge into the injectors running it, Zmax sells a fuel system cleaner, or there is one called RUN RIGHT, I would try putting some of that in letting it sit a few min then after it sat a few to soak in and break down the sludge, then start the car up, kick your idle up to around 1500 RPM do not go higher then that cause you will damage the engine, try that and see if that works for you, if not then I is probably the fuel pump or filter.
hope this helps.

SOURCE: I have a 1999 grand prix gtp that shuts off when

I'd definitley look at the fuel pump resistor first. Otherwise I'd say it's the fuel pump. But to find out before you spend too much money it may be worth your while to change the fuel filter, that will at least help whether the pump is bad or not.

SOURCE: Check Engine Light - P2181

Hi,first thing your cambelt and tensioner should have been replaced 13k miles ago,it would pay you to replace the water pump at the same time as they are known for impellor failure = cooling system fault=P2181 code,hope this helps.
