Had same problem, as if Kill switch was hit; believe it was deteriorated engine stop/run switch connector inside nacelle. Cleaned connector [22], Right Handlebar switches, applied dielectric grease, now solid, but still too early to celebrate.
May this be helpful: At first, engine would cut out while riding, cycle ignition key and run/stop/run switch, restarts no issue. Then required multiple cycles. Happened about 5 times while riding over 3 days.
At home, found 2 intermittent symptoms:
1) Diagnostic mode returned ‘no rSP’ on the ECM test, first P. Requires Eng switch in Run position to display a code or ‘nonE’ and then the Pn. It was.
2) Ign ON, Engine switch to Run: Fuel pump would not prime and Eng light would not come on for the initial 4 seconds.
Otherwise all normal, Security key on for 4 sec, then turns off and stays off, ie no codes.
Dealer was out of stock on Stop/run switch, so :eam checked pin 3 and 4 of connector [22] (Run switch) and found switch itself to be consistent and solid. Cleaned and greased pins; no more symptoms; so far all good.
Hoople is right (no surprise here):
… ‘with a "hands Free" FOB, once the engine is started, the FOB no longer has control over the ECM/TSSM…’
Check: Start up, walk away with the FOB, motor keeps running! I would think it’s also required to allow startup with the pin.
