I had this issue with my 2000 Grand Prix GTP. Apparently, there is an advisory about an issue with a resistor that fails and causes the symptoms that you described. My mechanic repaired the issue after first checking the fuel system and changing the fuel pump but without luck. Although, I didn't see the location of the resistor myself, he said it was accessed from the bottom of the car and that the resistor rusts due to exposure to the elements until it finally fails.

Car keeps shutting off while driving. We have changed fuel filter twice worked good for a couple of days and then started again. Any ideas what could be causing this?


Fuel filter is the best place to start but sometimes the fuel pump can cut out intermittently as well and it is also possible that your injectors are gummed up. Perhaps a higher grade of fuel might make a difference or fuel injector cleaner once a month when you fill your tank might help if it is an injector issue.
I am not certain how to tell if the fuel pump is intermittently cutting out other than eliminating other reasonable possibilities. I had that happen to me and like you I changed the fuel filter and ran injector cleaner through my tank and still had the problem. I dropped the tank and replaced the pump and it ran great afterward.

could be your anti theft system needs to be reset. turn your key to the on position for ten min, turn it off and then back to the on position for ten more min it should reset your key. anti theft cuts off your fuel supply so it can't be stolen

MY 1994 5.7 1500 RUNS FOR A LITTLE BIT AND THEN SHUTS OFF,I CHANGED THE FUEL PUMP FUEL FILTER,IGNITION MODULE.IT STARTED RIGHT UP AND RAN FOR ABOUT 20MIN.I THEN SHUT IT OFF & LET IT SIT FOR 5 MIN.IT...


You could have a fuel pump getting weak or fuel pump relay. One other thing to look into is the oil press. switch malfunctioning or loose connection. The fuel pump/relay get's it's power through this on some GM vehicles. If you have a haynes manual look at it's wiring diagram to verify.
