When hot engine begins running rough and dies. Will restart but runs very roughas if missing. Pop the hood and wait 15-20 minutes and will restart and run fine. Have replaced frt O2 sensor
In my opinion, this sounds like a good candidate to be put on an engine monitor. It could be so many things.
Its called vapor lock, you might need a fuel pump.
That's definitely one possibility
I would guess temp sensor or crank position sensor. Sometimes they will start giving improper readings without tripping the check engine light. You might also try disconnecting the computer and checking the timing
