Same incident here. After a few disturbing ignition cut-offs on mountain roads, I parked the bike on its sidestand. It started immediately. I resumed riding for a few miles (so the sidestand was NOT the issue, right?) , then it went dead (ignition, gauges, everything). I parked it again. And it started right away. It took me a few similarly disconcerting episodes to realize that as long as the bars were turned left, which is a natural parking habit (isn'it?), everything looked alright. But the very second I was turning the bars in the hope of hitting the road, the bike went dead.
What had happened (in hindsight) is that the wire you refer to had gradually dissected itself. Given the (questionable IMO) way it's routed, electrical current only flew through a few stretched filaments as long as the bars were turned left. Then it started flowing sporadically. Then it stopped flowing. By then, the wire was broken for good. And I called for road assistance...
PS Something to ask your dealers to pay preventive attention to after 2-3 years of ownership?
