I been having starting problems with my 94 camaro z28 after driving it for a while. It will start up fine all the time but when I drive it for awhile it has a hard time to start up- the longer I drive the car - the harder it is to start. Could this be -caused from the starter getting hot

 

I would guess the ignition coil is getting hot. It's bolted directly to the block so it soaks in a lot of heat directly. A lot of guys put a few washers in between the block and the ignition coil to help with that. Give that a try and see if it helps.
