I have a 2000 Pontiac Grand Prix that keeps shutting off while driving. Been an on going problem. I cleaned the battery connections because they were bad but other then that i am kind of at a loss. It start right back up if you pop it in neutral and start it but tonight we had to crank it a few time and wait a few mins. After we got it started it died again within a mile but started back up right away while coasting and got us the 5 miles home. Kind of leaning towards a fuel problem. Was wondering what everyone thought and if anyone knows of any test to find out more. It just comes and goes.

check fuel pressure and spark from the coils. see if they are all sparking with the same intensity. one of 2 things either the ignition control module is bad or the fuel pump might be going bad.
ok well if it's doing that then it probably isn't a coil pack going bad. usually they will produce a very weak spark compared to a good coil. i'd start looking at wiring issues and or the ignition module going bad. ICMs will usually fail when they get hot.
