43 is power to fuel pump and injectors. Check your fuses.
Code 43 = power supply to fuel injectors and fuel pump is not normal.

i would be checking the wiring, sounds like issues since fuses usually blow for a reason.

wires run off battery to the fuse block then off into main wiring harness where to go from there or easier to take to the dealer and let them worry about it

You don't happen to run your sled with a tether switch do you? I had that code pop up once, come to find out my tether was not completely seated.

No tether was wondering if anyone had a wiring diagram for the 08 fx nytro

Because there have been so many problems with relays I'd start there. If a relay gets wet enough it could short and cause a fuse to blow.

it happened to me a couple of times only when the temps were real cold. i put HEET in the tank andwaited 20-30 minutes and went to try to start it and it fired right up. i think its thepump getting froze. just my opinion

Had this issue with my 08 a couple years back. Turned out the fuel pump died, dealer replaced it with a new one from a brand new FX Nytro still in the crate out back at their dealership. They tested relays and fuses, but in the end, it was the fuel pump itself. Never had any issues since. Turn your key to the on position and listen for the fuel pump. If you don't hear it cycle, you're more than likely in the same boat I was. Hope this helps
