Right off it sounds like a component gets too warm and fails, but works cold. Is the engine getting fuel when warm? Does it have spark when warm? Knowing the answers to those questions as well as make, model, year and engine size would help to answer your question.
I had a similar problem with a 1987 Chevy Celebrity. I replaced the ignition module and the crankshaft sensor and it runs fine now.

Why will my 1988 Celebrity start when cold but wont start after car is warm?
What probly is going on is that your ignition module is failing. You can take this part off and have it tested, but the test will more than likely be false because, like you said, it only fails when warm. Start with replacing it with a junkyard part. This way, if it doesnt solve the problem, your not out the 100 bucks that the parts stores want for it.
