Help power cuts out while driving engine stays on

[3rdgenram94]

So I have a 02 3rd gen 4.7 dodge 1500.

Just today I was driving floored it to get onto the highway and once my truck passed 4000rpm. Everything electronic turned off on my dash my radio everything. The engine stayed on and as soon as I let off the lights and everything came back on. There was a air bag a seatbelt light lit up. Everytime now I pin it and it reaches 4000rpm same thing happens.

Id appreciate any help. I've called dodge and mechanics and nobody has a clue or heard of such thing.

Maybe a ground from the engine to the frame is loose or has some other defect. When the engine torques up it could pull enough to create a problem until it returns to natural state. Good luck.

I appreciate the response. It got worse anytime now my foot is even touching the pedal it's dead. I will for sure check the grounds. I appreciate it any other ideas.

Any updates on this one? I'm having a bit of an issue with my dash power. Same thing but I only lose power to my dash, which instantly powers back up (but I lose cruise control if it's on at the time it happens) every time I hit a bump or rut
