wow alot of things have been done already. do you know what the fuel pressure is at the frt fuel filter. it should be like 60 lbs while at cruize.did you repl frame rail pump with motocraft or aftermarket BECAUSE aftermarket will not keep f.p high enough to keep eng running at times
yes its a motorcraft replacement pump from the dealer,could the fp regulator cause this problem?
