Sir.
I had the exact same issue.
only mine only did it in gear.
dimming lights and everything.
I can honestly tell you I do not know what fixed it.
Was either bad o2 or bad cps. it could have also been the fuel ballast.
I messed with all of these one day.
2 years later now no issues.
My suspect is that it was the ballast
Mine happened after full engine rebuild.
I dont have the video. I looked.
did it for 2 months before I cured it.
make yourself an inline fuel pressure gauge. its the best $30 I ever spent on the jeep. That will tell you if its the ballast.
