Ok I have no clue what is going on.
I looked at the wiring diagrams, ABS & FUEL delivery & find no link.
So WHY I ask when I hard accelerate & the truck hits around 3,500RPMs does the ABS fuse blow causing no power to the fuel pump (in the tank) ???
OBD Code that is interesting: P1318 ABS Rough Road Line High Fault
cause a short would it? or just a dirty sensor?
Any help would be GREATly appreciated.

 

So at 3500 rpm, the truck cuts off, coasts to the side of the road, and won't crank up again until you replace fuse 4?

If it cranks back up once you have stopped, and does not need a fuse replaced to get pump started again.... perhaps Vehicle Speed Sensor (VSS) is about to fail (you can unplug it for testing - won't have speedometer - the VSS cuts engine if you exceed takeoff velocity, when failing can do that at much lower speed.) Rebuild article in tech area.

Or somehow your Inertia switch is triggering, on firewall, maybe it is not reset firmly. Breaks fuel pump in crash.

 

It's no surprise you call it "Puddles", soon you'll need to change it to "Incontinent" cuz you keep kicking it in the nut sack.

How about a broken motor mount or two. Check them and your ground straps to frame.

 

Along that path, the loose ground can make alternator volts shoot up to 17 or better, or alternator can just be bad and putting out more than 14.4 volts. You can test for ground bond issues with a battery cable from negative post to something sturdy on the engine. Voltmeter is handy.

 

The ALT sounds like a good start, & yes the #4 ABS completely fries.
I have done the VSS & the inertia switch previously (the VSS is the one with the small heat shield on it correct? if it is, then that's the one my brother broke off & didn't tell me about)<----the LAST time he every worked on my Disco!
