Unhappy Losing towing power

I have a 2005 2500hd with Allison transmission. When pulling 5th wheel loses power when going up grades. I have to pull over shut off truck wait a out 1 minute and I then have full power again. I have replaced the air filter and fuel filter but still have same problem.. Truck runs fine all other times

Any suggestions as to what I might do to fix problem would be appreciated.

This is a long shot but I have seen similar problems caused by debris in the fuel tank. Under load and increased fuel flow demand, the debris would restrict the fuel pickup in the tank. When allowed to sit, the debris would settle away from the fuel pickup and allow normal flow until it plugged up again.

also listen for the cooling fan. If you can hear that is has become louder, the engine may be running warm the cooling fan is engaging more. A cooling fan under full power can cause a lack of power concern. You did not mention if this truck was a diesel or not. I dont think GM uses electric cooling fans on gassers but if it is a mechanical fan, this could induce what your noticing.
