2000 Stalling out at higher RPM's

My truck runs fine for the most part until i have to step on the throttle, going up hill/ towing. As soon as I hit 2k or so rpm it bogs down and has no power. Normal driving it is fine. When it bogs down it does not smoke or anything, no codes. I changed the fuel filter and seemed to fix the problem for a week or two but is now doing it again. It is a 7.3. Any ideas.

Thanks

That last statement points to a possible restriction in the tank. A fuel pressure gauge will tell the story. You want to check fuel pressure under load. Spec is 55 psi plus or minus a few lbs. At wide open throttle and heavy load, the pressure should not drop more than 8-10 psi at most.

Here is a link that talks about checking the mixing screens inside the tank.
This is for a pickup truck...if you have a chassis cab then the tank is different and located behind the rear axle. Either way the procedure is about the same once you get the tank down. If you have a chassis cab truck, then you should be aware of another potential issue with some sort of interior tank lining that can flake off and also clog the screens.
