This happened again tonight, 2nd time. Bike is only 6 months old. It cranks over normally (not a slow crank) I don't think it's a low voltage issue. I'm a 20+ year high end automotive dealer tech (master in my brand). I completely understand low cranking voltage issues. It cranks over normally, but just cranks and sputters for 5-6+ seconds. Seems to be software related in my opinion.
My '06 R1, '07 FZ1, '17 FZ-10 or '13 R1 has never done this....
