Change fuel filters starving for fuel.

Sounds like a fuel issue. Have you changed the fuel filter ?

Very odd. A Google search comes back with lots of "Duramax" hits . The code is: "Fuel System Leak Detected - Large Leak"
Some fixes that I found were replacing the fuel filter, others changed the FPRV (Fuel pump return valve?)
When you're pulling a trailer there is a much greater load (air resistance) even when just cruising. Empty or fully loaded, it's mass won't matter, it's the extra fuel required at every phase of your drive. If the fuel filter is getting clogged, it's possible that some sensor is showing a pressure that is beyond predetermined limits. Try the fuel filter replacement first to see if that fixes it.

The Duramax fuel filter assembly is bad about sucking air. Replace the fuel filter assembly. It comes with a new fuel filter.
I need some good feedback.

I would suggest checking the water sensor in the bottom of the fuel filter. It's made of plastic and I've heard of them developing small cracks.

does it throw a check engine light?

Check your " FUEL FILTER " for clogging. Work backwards toward the fuel supply tank, Hope this helps.
