Re: NO start when hot!?
Fuel pump relay is possibly on the fritz. I had the same problem (annoying in the staging lanes).
replaced some grounds - no go Fuel pressure checked out - no go then I decided to hot wire the pimp via connector in engine bay harness - kept the pump running and it started.....every time. Replaced the relay and no problems since.

Re: NO start when hot!?
I don't mean the hot wire kit. I mean the fuel pump "hot wire" in the engine bay. The grey connector. Put 12 v to it and it will start the pump. I would recommend at least trying that to see if it will start when hot.
