Ryker goes into neutral while riding - any ideas?

[blackphoenix38]

I have the weirdest issue that I can't reproduce on my own.

While riding, I see on the LCD display the F will flash to the Neutral sign and then back. Sometimes it stays longer than others.

It doesn't affect the bike while I'm moving, but if I stop while it says it's in Neutral, it won't move until it goes back to Forward.

The gear lever does not move at all. I also had one time where it didn't know the parking brake was up, but that only happened once. Can't reproduce that either.

I put electrical tape over the ends of the gear position sensors in hopes that it would work, it hasn't really.

Also... this only happens on the highway on long trips over 50-75 miles. But once it does start, it doesn't stop happening for a while. I jiggled the gear position wires for a bit, and I was able to ride home on the highway for 75 miles with no issues at all. Nothing makes sense.
