2021 Honda CRF1100 Africa Twin

The fuel guage hits empty after only 3 gallons with a 5gal tank, did not do this when I first bought it, started after about 1200 miles on a long road trip. The TFT resets on its own, mileage for a tank will read for instance 22mi. when it should be 140-ish. It has reset while riding and on occasion between turning off ignition and restarting. At what point does this affect the automatic trans mission? The DCT is shifting up into 6th before 30mph creating a bog down situation. The resets also happen while operating on the road, just not when stopped.

While overpassing a slow moving truck doing about 45 MPH on a 2-lane highway, I accelerated to overtake the vehicle. Just before pulling in front of the truck I experienced a total loss of propulsion. I thought I had a broken chain. I quickly looked and discovered the chain was intact. I could rev the engine, but it would not go in gear. This is a Dual-Clutch transmission model. Unable now to overtake the truck and with traffic oncoming, I retreated to the shoulder on the far side of the road. The engine remained at a fast idle, but unable to get it in gear, I shutoff the engine. When I restarted the computer, I could not start the engine because now it was stuck in 3rd gear. After multiple attempts I was able to get the back to downshift to 3, 2, 1, then N by simultaneously rolling the bike back and forth while pressing the downshift button. I was able to ride the motorcycle home approx 165 miles without further fault but this could've ended badly.
