Have you actually verified that it's not getting fuel
by either disconnecting a fuel line or installing a
fuel pressure guage, because your problem seems more
like an ignition module or another type of electronic
component like a TDC sensor becoming unstable when
hot.
If you don't get a TDC signal or if there's another
electronic component preventing ignition, then the
fuel
pump won't run on most modern cars. I don't know your
car, so I can't be more specific; but I would be
looking at something like that.
