Problem resolved

Turns out it was the fuel pump. Dropped the tank and switched out the pump, now it runs like a champ. Thanks for the suggestions.

pokey iluvfire is correct. The fuel filter (at least '99's) is in the tank and supposed to last the life of the vehicle. Did you check to see if you have any codes?

Jp90Talon Well im pretty sure there is a filter on the pick up of the pump...I would def consider that.

iluvfire The 99 Wrangler doesn't have a seperate fuel filter. I believe it is part of the fuel pump. Talked to a few guys down here, went to a parts store, no fuel filter on the 99.

99 TJ Acceleration Problems

Driving down to Moab today I ran into a strange problem. My jeep was about out of gas and started to severley hesitate when I accelerated. Filled it up, continued driving with no problems until about 70 miles later when it did the same thing full of fuel. When I try to accelerate it sounds like the engine shuts of then it slows down. It typically happens at higher speeds like 60 accelerating to go faster, and gradually happened at lower speeds. It is the 4.0 liter engine. It drives fine at lower speeds like around town, but I need to figure it out to hit the trails and get home. Has no fuel filter and I checked the vaccuum line, so I am guessing a fuel pump or computer issue. Any ideas out there or suggestions of mechanics down here in town? Thanks ahead for any feedback or assistance.
