Lots of things to check - here's one more.
I had the same problem.
When cold, it ran, when warm it would die intermittently. Sometimes it would restart, sometimes not. I never had it towed because I could always go back a day later and it would start fine.
Swapped out lots of parts. No fix.
It ended up being the connection to the throttle position sensor was badly corroded. The sensor wasn't malfunctioning (car would hunt for an idle speed or race at idle and then die if tps was bad) - it just had intermittent contact. The hotter or more moist it got in the engine compartment, the less it would run. So no actual symptoms of tps failure - it would just die and not restart.
Total cost of fix - $2.39 for contact cleaner and an old toothbrush.
