Most likely it's the kill switch contacts or the fuel pump which doesn't always die once and for all. The biggest test is key on listen for fuel pump prime, if it doesn't try turning the kill switch on and off and wiggle it to see if it primes. If that gets it going fix if replace the switch, if not do the checks in the service manual for the fuel pump. You have one, right? If not, get one.
If you use the engine stop switch stop using it and use the key only. Both it and the pump are common problems and failures on these bikes.
