Duramax 6.6 2500 Diesel Problem

We lost power on a trip last summer and the Chevy garage told us it was just the gas cap not being tight enough. Seemed to work but it's happened twice since then even with a new gas cap plus we had a loud knock! Not fun when you are pulling the rig. Took it to our mechanic and he said we needed a fuel injector control module as well as a hydroboost and rear differental pinion seal. Anyway got it back yesterday after 2 weeks and $2200. Drove it last night and the same darn thing about 12 miles into the trip! Frustrating!! Any suggestions. Thanks!!
