Did you ever get a solution to the problem? The same thing is happening to mine.
2000 Jeep Cherokee, 4x4, 4ltr, 130k miles:
Intermittent engine cutout:
Sometimes engine keeps running after a momentary cutout:
But if engine stalls it can be restarted immediately:
Happens only a couple times a week and no more than once or twice a day even when driving long distances:
No computer code is thrown:
All instruments stay on except RPM will go down:
No warning lights.
Re-plugged all engine harness connectors,
Replaced Automatic Shutoff Relay,
