No Power

2001 f250 Superduty, 6spd manual with 140k miles. Truck was running fine. Went to the gas station turned the truck off and fueled up (with diesel). Left the gas station and truck was running extremely sluggish (idled fine). I could put my foot in it without much response seemed like it would start making power at about 2300 rpm or above. Any inclines that I would normally take in overdrive I would have to shift down and really have to put my foot in it to maintain speed. Like I previously mentioned I really had no acceleration when under 2200-2300 rpms. Drove for about 100 miles this way, stopped for a soda turned the truck off. Re-started the truck and it appeared all was fine. I still notice it being a little sluggish but not near as bad as it was.
Any ideas ???:shrug:

Maybe your CPS (Cam Position Sensor) Someone else should chime in with more answers. Did the check engine light come on. If so get the codes read from the comp and that will help.

No real funny sounds, didn't have my windows down though. No check engine light, I did replace the cps about 5k miles ago.

you probably wouldnt notice any funny sounds from the ebpv unless you had the windows down and a straight pipe.
do you have a boost and pyro gauge?

Maybe a turbo hose/boot blew off???? This same thing happened when I test drove an '04 6.0 at a local Ford dealership. I would floor it and 40mph is the best it would do then i would floor it again and it would take off like a freakin rocket!

if it was the EBPV y would it clear at higher rpm? how low were you on fuel before you filled up? i would check fuel filter and FPR
