limp mode
I have a 1990 Cherokee limited with a really unique problem. After driving highway for about half an hour or on backroads or about 45 minutes it starts to chug and try to choke itself out. If I drive for a few more minutes it will choke and stall wen I stop at a light or sign.
As far as I know I've done all the work needed to stop this, including plugs, wires, ran injector cleaner and seafoam multiple times, even fixed a vacum leak on the throttle body. I'm out of ideas and could use some help.

My Taurus SHO was doing the same thing, It felt like all of a sudden it lost power and was trying to die. Turned out it was the ignition module, worst of all it never threw a check engine light

Have you tested your sensors?
Throttle Position Sensor
Crankshaft Poisition Sensor
I would check those out
