LML Help!! On road trip home engine power reduced

[dylon333]

2011 lml. Deleted stock other then deletes. Driving down interstate on our way home from 2 HR drive truck keeps going into reduced engine power, no codes no rhyme or reason to it. Very intermittent. Shut truck off restart it and it's fine for a while again. When it happens throw it in neutral and rpms stay at 2k shut it off restart it and jumps back to 2k and hangs there. Only does it on trips. Doesn't do it during normal drive to work or anything which is 45 mins one way.

Plugged fuel filter?

Sounds like a tuning problem

 

[dylon333]

New filters, .... Tuning was my thought at first but was hoping someone had some other idea. Tuned by ppei

No single tune, just a 50 hp I think it was

Are you pulling a trailer?

 

[dylon333]

Yes both trips it did it I was pulling our gooseneck. We did find the maker light wire had come loose in connector but don't know how that would cause this
