Ben -

I am coming into this thread a little late in the game, so forgive me if I
mention something that has already been brought up.

My V8 has not liked being short cycled (started, moved in the driveway, and
shut off) since day one.  I have learned to make it a habit to let it run
for a few minutes, presumably to allow the engine management system to lean
out the mixture a bit.  I have never had a no start that I can remember, but
it is hard starting after a short cycle and it definitely runs very rough
for a minute or two once it starts.  It is very possible that the FPR is
dribbling a bit allowing fuel in while it is off, but my guess is that it is
nothing more than a very rich condition at start-up.  By the way, changing
out the FPR is pretty easy and is probably a good idea if yours is old.

Sounds like a bad Fuel pressure regulator.
