Car starts fine when cold, after it warms up won't start for 5-30 minutes,checked fuel pressure,fuel pump,had ecm checked,it was good,replaced crankshaft position sensor,still does the same thing.Need answers or suggestions

Depending upon the year of the car, I would replace the Ignition Control Module (ICM). These are problematic components that I recommend replacing every 120,000 miles or 10 years, whichever comes first. Easy job.
