I have a 2007 chevy silverado 2500 hd duramax diesel. the truck goes into limp mode when i pull my dump trailer and then engine shut down the last time.what could it be? (she runs fine if i am not pulling anything)
Mo me it sounds like low fuel volume i would check my lift pump
i have this problem with an 01 chev had me replace the fuel pressure regulator500.oo and the fuel filter can cause this if it isnt big enough. dont use after markets. neither fixed the problem. the code reads massive fuel loss. im down to reprogram the ecm if that doesnt do it im looking at the fuel recovery valve

After driving for awhile the check engine light comes on and the truck goes into Limp Mode...
