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.

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
