fuel pump possibly. not enough fuel delivery. Throttle position sensor, or map sensor. I think 97 TJ may be OBDII, but I'm not sure on that, with a scanner you can check those sensors. also check ignition system verify its not a misfire from lack of spark.

When was the last time you did an ignition tuneup? I had a similar issue (jerking under load) and replacing the ignition parts (plugs, wires, cap/rotor) fixed things. I suspect the plug wires had gone bad.

Any codes?

I had something similar from bad spark plug wires grounding out.
