Battery Propulsion System Problems of Jeep Wrangler

While driving, the vehicle loses propulsion; the rpms go to zero for about 3 seconds and then return to normal and acceleration is regained. No check engine light or code is given. This occurred randomly for the last year. In June of 2020 I took it to Jeep dealer who was not able to replicate the problem and said that no code was given. Then in December of 2020 the issue became worse to where the vehicle would completely shut down and not regain power unless restarted. On one occasion it would not restart, leaving me stranded. I took it to an independent mechanic who also could not replicate the problem. The independent mechanic suggested that the symptoms sound like they are related to a fuel pump relay, but that part is not replaceable on my Jeep. They said that other Chrysler vehicles have had recalls for similar problems, but not my year model Jeep. The problem continues to persist randomly. Sometimes it happens twice within an hour, sometimes not at all. When it happens it's always in motion. On January 16th I video recorded the incident while driving. I have the entire thing on video that I can share with you. In the video you can see that I'm driving at a steady speed at 2500 rpms. Then the rpms flash quickly to 3500 rpms and then instantly drop to zero, as though the ignition had been turned off. Although I still have electrical, as my radio and blinkers are working, the Jeep very quickly loses power steering. If I had not been able to quickly pull off the highway my Jeep would have been dead and stranded in the middle of a busy highway. I then attempted to restart the Jeep, but it would not start. I would turn the key just once and let go, but the Jeep would continue trying to start over and over for about 10 seconds before stopping. I was unable to start the Jeep until waiting for a period of about 10 minutes. Then it started up and operated normally.
