It does NOT lose electrical when this happens so it is NOT the main circuit breaker which has been updated. Temperature of bike doesn't seem to make difference and neither does fuel level. Two or three times it has shut off long enough for me to coast to side of road and re-start WITHOUT cycling run/off switch--I just hit start. Last time was in middle of intersection when I was starting from stop. Took a little more for it to start that time but normally starts right up. Runs and starts awesome the rest of time. I have thrown a crank sensor at it to try and fix problem. Only once did the check engine light come on when it died and stayed on for short period of time otherwise it doesn't. MODS done to bike are Bassani slip ons, stage one kit and power commander. This problems was occurring before any mods were done. I have scoured many forums for help. I also have the service and diagnostics manuals which don't help with intermittent problem. Thinking along the lines of bank angle sensor, ignition switch or maybe run/kill switch. Fuel pump was replaced in 2013 and I have "wiggle tested harness. Any advice is greatly appreciated----cannot trust bike at all
