It wouldn't hurt to check the ignition switch and the starter solenoid, but I have a feeling your battery is giving you an early warning that it's about to give up.
Mine stalled out the other day and would not restart straight away, but it was hot and the fan and headlights were on, I've now got a new battery ready to go in.
For Tech Questions Bike Model letters and Country are more useful than saying the year, for UK owners anyway, as registration year is not always the year of manufacturer model.
