Whereas there are dozens of things to be aware of with this engine, focusing on your symptom, I'm wondering if the fan clutch is sticking on unnecessarily. The fan clutches in the early 6.0L equipped trucks could fail.

Hang on - another thought...
Did the turbocharger itself get repaired? I would have your turbo checked for a seized Center Housing Rotating Assembly (CHRA), and/or sticking turbo vanes from coking. If there is anything jammed up in the turbo, you will have a loss of power and you will also have abnormal noises.
If you have it checked and find out this is the case, report back here, and I'll give you some more insight on things to be sure of in the repair process.
