it almost like the engine dying out, kinda like lettin the clutch out with no throttle..

It has to be from the transfercase, tranny, or clutch, i have checked everything else.Any ideas how to check the tranny and t-case? It only does it under a load FYI. the shifter jerks and the hole truck jerks really bad?
Is this what yours is doing 4byRanger??
