Sorry if I put this in the wrong section I'm new!! Truck runs normal at low rpms but if I push on the accelerator too speed up it loses almost all power and just sputter and bogges
down. Ran fine before and well maintained truc,

Losing fuel pressure? maybe a partially clogged fuel filter. Have you checked the fuel pressure?

Sounds like low fuel pressure to me too.
