happened to my new 2020 Rebel. Truck had 700ish miles when I bought it. The second day I had it, it went out while I was driving. Took a pic. Got to my destination turned on and off like 3 times and no change. Went in and called the dealer, service said bring it right in. Got in the truck (still out) and was there in 40 minutes. they took it right in, came back and said ummm this is working. I showed him the pic on my phone and said I did like 4 full full off and on restarts. They put it up for codes just in case...no codes...we are now treating it as wait and see. It has not happened since and I am maybe 700 more miles. Best of luck to us!
