Only when hot I have no power. I have toi feather the gas just to move. At 65 on the high way if I go to pass as soon as it shifts down it bogs down and looses all speed and again I have to feather the gas to get going. Anything more than 5% of the pedal and it bogs down. Again only when its ran for awhile this occurs...While cold it runs perfect.

At a total loss now!!!
