89z24
The car will start fine, run fine, but after driving for 15 or so miles it will quit and will not start until it cools down from operating temp, I am at my wits end, have changed computer, map, iginiton module sensor and it does a little better, help anyone.

Re: 89z24
You need to find out if it's spark or fuel related.
Let it run until it dies/doesn't start. Remove a plug wire, install a spark plug into the boot and lay it on anything metal. Have someone crank it over and check for spark.If it has spark, it's fuel related. Shoot some carburetor cleaner into the vacuum line for the fuel regulator (or any other intake vacuum source) and see if it will start. If it does, it could be as easy as a plugged fuel filter, worst case would be a fuel pump. If it has no spark, it's surely ignition related. I'm not w/which engine you have. I have replaced bad crankshaft sensors for that same problem.
