I have had issues with my old girl. She is a 97 tl1000s. She started bucking and turned off and showed neutral light. We tried everything. Then with a lot of help we found out that the Tre was having issues. There is a small diode on the right hand side of the bike near the gas tank where your knee is. It is tapped into the main wire loom. One leg is failing on the diode in this. The diode looks like a fuse when untapped but instead of two legs like a fuse it has 3. I will show more on this shortly and how to find out what's wrong and were to get a replacement.
