1997 Blazer Base Model wont start

The problem is when I drive my blazer and it heats up i will turn it off and when i go to start it again it won't start or even try to turn over. The temp has to go back down to about 100 before it will start. As soon as it's cooled down it starts like there is no problem. The check engine soon light doesn't come on or anything. I have replaced the starter, ignition module, and the ignition coil. None of them helped. Can anybody help?
