Or pour cold water on the sensors ... I know this trick works on the
5000 , and the sensors on the V8 are very similar .

When you hear hoofbeats, think horses, not zebras. ;-) What the other
guys said, only I'd lean more towards the usual. This is THE symptom of
a bad reference sender. When bad, the sender sends a signal when cold,
but opens the circuit when hot, no signal=no run.
The location of the fuse box on lesser type 44's seems to be a major
contributing factor to the early demise and corrosion of contacts for
the Fuel Pump Relay. I have had the Fuel Pump Relay problem noted, but
not while running or on any of the V8Q's. To rule it in/out keep a
piece of wire with 2 spade connectors handy, when/if the car dies,
jumper the Relay and see what happens...I suspect nothing, but still
hoping it's that, since it's the easiest of the fixes.
