Scott--as we tell everyone that has an issue like you are describing, check the actual fuel pressure with a know good mechanical gauge tee'd into the FP hose. That way you can see if its a 'real' pressure fluxation, or instrumentation.

But from the sound ot things, with no other erratic engine operation, no surges, no rpm or map, cht, egt fluxuations, it points to a sender/wireing/ground/power, interface problem.
