1999 Chevy Tahoe acceleration problems

I have a 1999 Chevrolet Tahoe 4wd with the 5.7 liter v8 with 133,000 miles. I recently began having trouble when I accelerate from stop. As I press the accelerator, it feels as if the engine is "bogging down" and continues until I let off and accelerate slower or until you hear and feel a thump. I've replaced all of the spark plugs, wires and fuel filter, but the problem still persists. What else should I consider? Thanks for the help.
