Dead pedal from 50-100%

As title states my truck is becoming a dog, worse when warm. Pedal seems completely dead from half to full throttle. No change in engine reponse, noise, rpms, nothing ??????? When cold its had fairly decent power but ill have to get on it when cold here maybe tom and check on that.

Bad TPS???

the lack of power when warm says to me a problem with the HPO as it warms it thins and no longer provides the pressure you need. as if there is a cut/tear in the IPR allowing to much oil to flow past
