I had a failing fuel pump on a trip out west last year that just got progressively worst as the trip went on. Checked fuel pressure and it was within spec so I thought the fuel pump was good, so after changing wires and a bunch of ignition parts I took it to a shop. They were stumped also and thought it was a bad timing gear at first because the fuel pressure check out fine for them also. The thing I learned was there is a flow rate spec also that is needed to deliver fuel to the engine. Its kind of like volts and amps, just because you read good volts does not mean the proper amps are getting through. An easy way to tell if it is the fuel pump is to spray starting fluid or gas into the TB and if it keeps running it is probably your fuel pump.
