460 efi question

Hello I recently got a 97 f250 5 speed 460 to pull my camper. Ran good the first while but now has little to no power. Can really notice it in the higher rpm when the motor has warmed up. Any help to get me going in the right direction would be appreciated. Thanks!

Start by checking the fuel pressure. Sounds like you have either a failing fuel pump, stopped up filter, or a failing pressure regulator. If everything there is ok, O2 sensor would be my next suspect. Go ahead and pull codes to see what the truck has to say about it.
