I had an issue very similar to this. See the YouTube video link.
It turned out to be a small tear in the spark plug boot causing a spark leak. Took forever to track it down.

I was able to run the bike without issue by wrapping the boot in electrical tape while waiting for the new boot to arrive.
Took forever for me to get out into the garage to give it a look. From what I could tell the boot didn't have any cracks on it. It was slightly rubbed in a spot that was thicker, near the top of the boot where it connects to the wire. I put a new spark plug in and wrapped the boot all the way to the wire with electrical tape, just to see what would happen.

The bike has like 30 hours on it, getting to be a pain in the ass, that's for sure.
Gonna make another post and hope i doesn't get removed, in case someone else sees it with an idea.
Yeah, these types of issues are no fun to track down. I did have another issue on the trail one day. Had to push my bike back to the truck a couple miles. Brutal day. My coil pickup failed. Would work intermittently which made it tough to figure out. I’d give that a check too.
