Cannot restart after the engine has been driven for a period of time and is hot. Running good not showing any trouble alarm so haven't check for codes. Will crank over but no fire. Once cooled down for approx. 20+ minutes may start as normal. Not overheating.

Good morning,

When it will not start, you need to test for spark and fuel pressure to see which system has failed.

Once you find which system is not working, then we can narrow down the failure. Let me know the results of the checks.
