Bogged down While In Gear And Sputtered During Acceleration

My 4x4 started coughing and spuddering, on the way to the junkyard. It would die, crank up and I would slam it in gear to get down the raod to the next light. Finally I was cruising about 40 and Kaboom it quit. I pulled the fuel line and had plenty of gas. I was in a bad neighborhood and it was almost dark, so I had it toed home. I went through a couple of ECUs because you can get a bad one brand new in the box. A buddy of mine change 3 sitting in the auto parts parking lot before getting a good one. Anyhow, I could not get it to start. I had a lot of trouble from this motor anyway, so I yanked it and put the one from my Dart in it. It still wouldn't start. I ordered a whole new ignition system from ProComp Distributor, coil, and wires...dropped it in and it's still running. They use a module on the side of their distributor instead of an ECU...no ballast resistor. I saw a few people on here had problems with them after I bought it. I assume that is because the tang at the bottom of the distributor shaft is about 30 degrees from being in line with the rotor. I actually moved the cam gear a couple of teeth over to make the rotor line up with number 1. Crappy design, but once you figure it out it works.

Rice Nuker might be right with his suggestion. I saw you checked your fuel pressure, but I still wonder if the sock in your tank might be starting to gum up. Yeah, I had that happen before too. I took the air and pressured up the fuel line. Pow...blublblublublub, and I had plenty of fuel after that. It is pretty easy to pull the line out of the tank, and it won't cost anything to look if you want to do it the right way. With all the crap building up in your fuel filters, you may not even have a sock. You could undo the fuel line at the pump and the one at the tank and blow some air through it. Yeap, I had a tank with all the crap in it that would clog up filters and leave me on the side of the road. The last time the filter was solid black it was so full of crap. When I pulled the tank to clean it, I discovered the fuel line was really gummed up, like a clogged artery. The gas stopped flowing and the cars heart stopped. I replaced the fuel line and tank.
