97 monte carlo z34 starting problems

I also am having problems with my monte carlo trying to start it. I drive it for about an hour or so then go to shut it off and it doesnt want to start again. Couple hours later it will start with no problem. Took it in to have a diagnostic test done on it and nothing wrong with it. Talked to a few diffrent mechanics and they gave me some suggestions. They said that it could be a module, fuel pump, cam shaft sensor, or a fuel injector. These are just some ideas for you to consider. Hope this might help you some what. If you have any suggestions for me I would deffinetly keep them in mind.

Ignition module, Camshaft sensor, Crankshaft sensor... When any of these are faulty, they are suseptible to heat soak. Will cause the symptoms you describe.
