Although I said that if I push the engine (say 3500+ rpms), and I can 
trigger it starting, and it will continue to plague me for the trip, what I 
perhaps didn't make clear is that it will do this even at lower speeds.  In 
other words, I get on the highway - hit 80 mph (about 3600 rpm, I think, in 
overdrive), maybe a couple of minutes into this it feels like I'm running 
low on gas - speed might drop to 60, or if it's really doing poor, might 
drop down to 30 m.p.h. (or worse).  I put the hazards on, get into the 
breakdown lane, and chug along.  Flooring the gas does nothing, sometimes 
coming up off the gas actually relieves it a bit.

I get off the Interstate, when my exit thankfully appears, and just drive 
back roads.  Twenty minutes later I'm still experiencing intermittent 
problems, even at a normal 40 mph drive with moderate rpms.

Had I stayed at 40 the whole trip, I might not have seen it, but having 
managed to set it off somehow (passing a car, going up a hill with speed, 
going on the highway), then it's back to plague me no matter what the 
driving style for the rest of the drive.

With that extra information, would that still be in keeping with the fuel 
pump diagnosis?  It strikes me more as some kind of clogging.

Thanks
