Voltage issue

So i think i have a regulator going bad, i have done some searching across the forum and wanted to see if anyone had ore thoughts on it. I haven’t done any test on the bike as of yet, been busy with work.

Took the bike off the trailer started fine, went riding shut the bike off wouldn’t restart, jumped the bike with cables, and didn’t shut it the rest of the night. Gauge cluster would show 9.4-10.4 volts with the accessories on(light bar, stereo). shut them off and the voltage would go off the screen. Bike ran fine the rest of the night, didn’t shut it off ran fine. Finally get back to the trailer shut it off and then restarted it to load it and started right up. could this be a voltage regulator issue?
