2. I recently changed the computer and it solved a lot of starting/alarm problems that were hounding me. But, whether related or not, my stalling problems have grown.
3. Now, in the middle of driving, I have had the vehicle's RPM's zero out and it either a) coasts a bit before kicking in again on its own; or b) It stalls altogether, I lose power, etc., and have to pull over in order to let it rest and start up again.
The strange randomness of the stalls have caused me to once again probe all of your mechanical minds. (PS, thanks to all who contributed to my computer problems. You are all so insightful - where did you all learn so much about Jeeps?!?)
Thanks again,

I had some stalling trouble( idle dropping to low) about a year ago and solved the problem very easily . I Replaced the PCV valve which probably was original. a quick $2 fix. Sometimes ya just gotta go back to the basics. I etired from 30+ years in car business. Regards ,AL
