1999 Pontiac Sunfire 4 cyl Wheel Drive Type unknown Automatic 000000 miles

I have a 99 pontiac sunfire 2.2L that has just had the fuel pump, fuel filter, throttle pressure sensor, and the fuel relay replaced. But the car still putters as if its going to run out of gas, back fires, then stalls out. If I restart the car, it will run ok for a little bit then do it again. What else can have checked?

First thing you need to do is have the codes read, Autozone does it free, Post the results with the code number(s). Even if the service engine light is not on, there should be freeze frame data stored.
If it won't make it to Autozone, buy a cheap scanner, they can be had for 30-40 dollars, a good investment, since they cover all cars sold in the USA from 96 on.
