What would cause your car to run fine until you shut it off and it wont start back up till it cools down but its not over heating then it just shut off going down the road

Begin your diagnosis with the "no-start" condition. Check ignition first - see if you are getting spark from the coils, and also check fuel pressure.

Either bad fuel pump hot on run, bad ignition module, crank sensor or head gaskets.

I had the same problem. The fuel pump was weak. Replace it. It is easy to do as there is an access cover on the right top of the gas tank inside the trunk. If you use other than an AC Delco pump, they are very noisy.
