Yesterday in central NY at 7am it was -24 degrees. I had the truck plugged in all night but it still strted hard. I drove it for a half an hour - running ok but not normal -figured it was really cold. After a half an hour the truck had no power - I noticed the turbo was not there. And let me tell you that without that turbo the diesel does not have much power. Anyway I headed directly to dealership which was not to far away. They told me that because the temperature was so extreme that the turbo wastegate closes to allow engine temperature to rise and then reopens to normal running conditions. I kinda believed it. Is this what really happened???

Man...if the dealer told you that regarding a 6.0 I would be really nervous about going back to those guys. Did anybody check to see if turbo hoses were split or blown off? Not uncommon.
Arm chair diagnostics at its best. The EGR circulates hot exhaust into the intake to help the truck warm up. Your VGT Turbo may not be operating properly for the loss of power issue your speaking of and some issues misdiagnosed with the 6.0L are coming from the barometric pressure sensor.

I have had the exact same experience in cold temperatures when using the block heater. Truck fire up fine, runs fine for about 10-20 minutes and the turbo is then lost. The only thing that brings it back is shutting the truck off and then back on. I'm guessing this is a sensor or programming issues.
It's happened to me 5 times now, ALL after using the block heater in very cold weather.

Take your pick, maybe a new dealer too.
That little booger is causing more problems than most realize
