1991 Jeep YJ 4 cyl Four Wheel Drive Manual

Hi I really need help with my truck, it seems like its running out of gas or the engine is missing im not sure, but I have change all spark plugs and the wires and I put a new coil in it and a new fuel pump, I also put in a new distributer cap and new resonator in the muffler, anyways we also got it hooked up to some analyzer and just an o2 sensor was wrong which was from the previously broken resonator and after all this my engine after going about 40 km it starts to die like its not getting fuel or the engine is missing and I dont know what there is left to do can anyone help?

When you changed fuel pump did you change fuel filter. It is usually recommended anyways.
