Starving for fuel

(1999 Jeep Grand Cherokee)
i have been working and researching on this jeep for almost a week. it is a 1999 jeep grand cherokee with the 4.7 v8. drive down the road get about 35 mph and it acts like it is starving for fuel. it will bog way down the more you step on the gas. get below the 35 and it runs just fine. replaced the crank sensor cause that's the first thing that i ran across on the research. what could be the problem?

Need to check for clogged catalytic convertor(s). When rev engine you should be able to feel difference at tailpipe. May have to take to shop for back pressure test. Old way was to seperate exhaust in front of cat or remove O2 in front of cat and see if power improves.
