Engine shuts off when warm

What is your question?

When engine is cold, engine starts right up and runs fine for like 10 minutes. When engine gets warm, stops running and when I try to start again there is no spark. Once engine cools down, starts up, runs, until warm again.

What makes this problem better or worse?
