I have ,a buddy with a 95 cherokee and the problem he's having is that he'll drive it for about 20 mins just long enough for things to get warm then it starts stalling out and sputtering. We've replaced cap, rotor, plugs, wires, gas cap .we've swapped parts from another cherokee same year to test things and still no luck please give your advise thanks guys.

 

Try the Crank Shaft Position Sensor.

 

We'll give that a shot.
