hi all i have a problem i cant solve.when i go down the highway at like 65-70 it bucks like its not getting fuel,so far i replaced the pmd (put it on a cooler).did that 2 times cant be bad.than i replaced the fuel filter and it was fixed.about 300 miles later it started to buck again so i replaced the filter again.ok fixed ya right another 300 miles later bucking again.so than i checked the lift pump that is good, than i replaced the filter again.at that time i took the old one apart nothing in it not plugged clean like new.than i tried to drain the filter bowl nothing came out of the valve????but i cracked the bleeder on top of the filter it squirted out and hit the hood, so i put the new filter in and it was fine for 300 or so miles can someone help????

Sounds like the lift pump could be intermittent.

Or the oil pressure switch contacts powering the lift pump could be intermittent, too?
