I have a 1994 Camaro Z28 that was running rough at one point then I corrected that, now I have this problem that if the car is cold it will run and run fine then as soon at it gets warm and I stop it will not restart. It will not restart until the next morning which means it takes along time for it to cool down. All things have been changed such as the basics, starter coil, plugs, caps etc. I am lost for what this maybe. I am in college and really need this car to run to go to work

check the fuel system and the vacuum lines.

I'd do two simple things before jumping into anything expensive:
1. Clean the throttle body
2. Check the fuel pressure when the engine is cold, you do this without the engine running. Just turn the key to the on position without cranking the engine.
After you have checked the fuel pressure when the engine is cold and not runnng, then start the car and check it again with the engine running.
Then, when you know the engine is hot and will not start again, check the fuel pressure engine running. Then shut it off and check the fuel pressure again.
The only other thing might be the catalytic convertor but when this begins to plug up from old age the car will stall and not restart until the exhaust gasses have escaped. This is more common on the 4 cylinder engines and less common on the V-6 and V-8 engines.
Ultimately, it sounds like the fuel pressure is dropping as the car warms up and it might be time for a new fuel pump.
Good Luck!

it could be that you throttle body butter fly valve is sticking and causing the engine to flood itself. Check your throttle linkage and get some throttle body cleaner and an old tooth brush. Take the hose between the air filter box and throttle body off at the throttle body and spray the body and butterfly valve down and scrub with toothbrush.
The car will be a little hard to start at first and then run rough do to the cleaner. But it will run better after a couple of blocks.
See if that works if not it more than likely is your timing jumped out.

If you changed the timing or didn't this more than likely the timing if it is turning over slow

flooding condition .... leaking injectors
