I think I have found the culprit. I put my fuel pressure gauge on the truck- 60psi even when driving and still no take off power. The SES light was not lit so I checked the DTC's and low and behold P0336 code but no light. I cleared it and drove it down the road to a dirt lane near my house. It would take off good. I drove it around more and noticed the power gone again. No light- Checked the DTC's and the P0336 code was back. cleared it and power was back. When I day power is gone I mean think of it as TM times 3 it is dead until about 2200-2500 rpm. If I have time tomorrow I am going to log it with HP and see what happens with and without the code.
