1999 Ford F-350 Super Duty Lariat 6.8L Hesitation, Cuts out, Stall, Misfire, MIL Lamp on
This truck is making me crazy. Customer reported truck cuts out under load. He replaced the fuel filter and fuel pump. He said it ran great for about 1 week then started doing the same thing again. They replaced the fuel filter again thinking it might be dirty...
