[V8] Fuel Pump Failure Modes

[Coleman, David]

Oh man that's the worst kind of mechanical failure -- you'd have been
dead in the water, had to pay for a flatbed, and then been unable to
diagnose because it ran again.   

Are there any codes now (or from yesterday that have disappeared)?
I've never had any fuel pump go bad then later come to life either...
Though just a thought, don't you have some crazy steep driveway?    Not
to discount your expertise in the least, but did you run out of gas, but
after sitting on a steep incline, the FP got refilled?

Otherwise... When it conked out, did it just die, or stumble before
eventually cutting out completely?   I assume it would turn over when
trying to restart, but did it sputter or almost catch when trying to
restart at all?
