Loss of power
I was pulling a 40ft 5th wheel up a hill and the truck lost all power until it dropped to below 40 then all the power came back. Then on thursday my mom was pulling a hill with just a 3 horse trailer up a hill and she said it did the same thing. Any ideas I havent pulled after and I need to use it again soon. The programmer is on tow preformance mode.
