The car starts and runs for about 20 minutes then it shuts down and wont start until engine cools. I have replaced the ignition module, coils and the E.C.M. Also it still has fuel pressure after it shuts down. what could be the problem?

check for spark when it's dead.
it's probably loosing ignition.

after you verify that there is no spark we can go from there.
