Started right back up and continued on thinking well I have insurance with a tow so screw it. A couple more miles the engine and battery lights turned off. Got to my destination about 20 miles away shut it off and walked away. The next time I started her the lights came in again about a mile down the road but shut off shortly after during the same trip. They haven't come back on since.

Can a battery tender fail causing a low battery hence low voltage? And by riding it charged it back up? Has anyone experienced a error code that showed up once and went away without any further issues?

Not sure where to start. I am ok with tools and doing minor to moderate repairs but I'm no electrician.
