Default Fueling issues??? Help!

In my '98 xj I can't seem to climb over 3250 rpm's. When I get up to somewhere around there it cuts out all power and starts to bog down. If I hold my foot to the floor when it tries to do this it acts as if its stalling. When I fall back down to around 2500 all goes back to normal. This is my DD and it make highway speeds difficult when I have to go over a hill. I'm leaning towards fuel pump or injectors myself. So I guess my question is which is more likely to have problems? And I can't find an in-line style fuel filter so I'm guessing its just got the little sock filter at the pump?

Fuel pump, but check the fuel pressure before you start dropping the tank.
