Sounds like to me the firing order is off, or you have your plugs wires backwards. Maybe a carb issue also. Check for a vacuum leak.

Why would your 2005 Chevy Cobalt stall after you drive it for a while?

The problem could be the Throttle Position Sensor (TPS) on the side of your throttle body. If the Rpm fluctuate when stopping also. Make note of this problem with the stalling. This is the most reason why it would stall. Just make sure the other problem In explained is there too before you go out and buy a new throttle body. I had the same problem with my colbolt and the throttle body cost was 255.00 that's with tax. So good luck.
