I'm hopeing that someone can point me in the right direction here is the most descriptive explanation of what is going on with my car:

I have a '92 Cavalier that is having a problem with stalling after driving for a while. When you start the car up, it starts up beautifully and runs great. However after driving for about 20-25 minutes, I can tap the gas pedal lightly and if the car jerks, then I know that when I come to a complete stop, the car will jerk and then stall out. When this happens, I can start the car right back up, however when I put it in any gear, except park and neutral, the car will stall right out. I usually have to wait 10-15 minutes before I can start the car, put it in drive, and then drive off. A sorta work around that I have found is to tap the gas pedal, and if it jerks, then I just slam the gas pedal all the way down. The car will accelerate very heavily/slowly, and then acts as if something gets dislodged and then the car will accelerate normally. From this point I can come to a complete stop and the car won't stall out. It will remain this way for about 2-3 minutes and then the problem comes back. I have replaced the fuel filter and yet the problem still exists, but doesn't jerk as bad. The car has done a lot of heavy sitting, and I have ran fuel injector cleaner through it, however I haven't ran any through the tank since I replaced the fuel filter. I have also tried a bottle of iso-heat, which didn't help at all. I did have a problem with water in the fuel system about a year ago, but I have taken care of that problem by running a couple of bottles of iso-heat through the tank. So I'm not sure if that is related, but I never had the problem until just about 2-3 months ago. That is when the stalling problem started up. Thanks for your help.

You probably need to replace the small filter that is in your gas tank. Your tank probably has rust in it from the water and it starts moving and hits that filter, blocking the gas. Just a suggestion. We had an R.V. That did the same thing, and that is what it turned out to be. However you must take off the tank.I reccommend taking it to a shop, and have them clean your tank and replace that small filter

I would have to agree, try reving it up in park, if it won't rev without being sluggish then I would say the fuel pump, try it when it starts having problems so you know the fuel pump is warm. If not before taking the tank off try spraying some (NON-FLAMMABLE) fluid around the base of intake(after warmed up)if it boggs the motor then your problem is an intake gasket that has shrunk and is letting to much air pass.

Try unhooking The TCC solenoid and driving it. Don't run it long time with it unhooked. If it is that the dealer is the best place to get one. 50.00

OK here is your fix.
The TCC is actually the problem. This was a Service bulletin back in the day. This is the GM fix for the problem.
The TCC connector is plugged into the front side of the transmission. The part in the tranny is white in colour, the plug should be blue. There are only two wires (although spots for 4) 1 wire is purple the other is tan with a black stripe.
UNPLUG this connector.
Disconnect your battery for about 10 minutes.
Reconnect battery and away you go.

The service bulletin was simply this.
Take that blue plug and tape it out of the way.
You must have had a service man work on your car and he saw the plug undone and then reconnected it for you without telling you.
Unhooking the battery will reset your computor.

Good luck
Let us know what happens.

I have a 91 cavalier. I had the same issue.
