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.

You have any check engine lights?

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

No engine lights come on, and I'll look into the rest of those. Tyanks
