Reduced engine power light coming on

So my reduced engine power light has been randomly coming on. Appears to only do it on highways? Came on today while I was towing on the highway. If I shut it off and restart it when i stop goes away but comes back when I get back on the highway. Any ideas? Still feels the same

I've had the same happen a few times, it appears to have stopped since I changed both of my fuel filters. Could be coincidence.

Mine was doing that to it ended up needing one of the thermostats replaced. Hope this helps.

On thanks the info, I'll have my mechanic change the fuel filters because I'm due for them I think and I'll see what he says about the thermostats. Thanks!

I'd think you would have a dtc stored in the PCM that would give a clue about what is happening

Truck goes in Wednesday for a new thermostat and new fuel filters so we'll see what happens. Hopefully this does the trick!

Well my mechanic didn't want to do the thermostats due to the fact of removing the egr so I guess I'll have to do them when I do my egr delete. Fuel filters were done and the light came on this morning still on my way to work

Yup, mine came on with a nice hard run on my way to work this morning too. Damn... I think mine is coming on from "overboost"... doesn't really happen until my boost needle is buried. Never happens in normal driving.

Mine happens alot when I'm on highways for some reason, I don't really accelerate hard but the boost needle is buried at 40psi getting up to speed or passing. It's been doing it alot lately, it used to be every once in a while.
