spit, sputter, pop..........?

I have a 90 2.5 YJ with manual tranny. I went wheeling Sat at Uwharrie, and I was getting aa slight miss every now and then and just ignored it thinking maybe some bad fuel.
Well as I went on wheeling it got worse, and eventually it would do it on every incline, and when it was under any kind of load. It even died a few times. It will idle fine for as long as I will let it, but under a load it starts the sputter/pop.
I am torn between pulling the tank, and replacing the crank position sensor.

Have you checked your fuel pressure? Ide do that before pulling the tank. Pull your plugs and check to see if they are running lean (end of plug will be light colored or white) or rich (black). Let us know what you find.

The crazy thing is that I went out and ran it through the woods tonight, and it is running great. I climbed tree stumps, hills and everything I could to get it to miss and sputter, and it ran fine

It could be the ignition coil breaking down. After it gets hot it starts to lose its spark

I am leaning toward a fuel delivery problem, but now it will not do it
