I have a 2003 F350 with the 6.0 in it 416,xxx miles new motor has about 100,xxx same as transmission I recently had a bad alternator on the truck which I believe fried my FICM so just to be safe I replace alternator, batteries, and FICM. Truck ran great then I put a Predator on the truck (which was on the truck when I bought but removed for longevity purposes) The truck performed great until I got up to speed then the truck would start cutting out around 3000 rpms (acted like it wasnt getting enough fuel) so got home and shut off truck went out to start next morning and no luck. removed predator and will start if I have been messsing with and tried to get to start for 20-30 mins with batteries being jumped from another truck continually once started runs fine. Am I looking at a fuel pump issue, Ficm, fuel reg sensor? oil pressure reads good any help would be greatly appreciated I just dont know where to start
