Am I just being a bit dim here?
Seeing as the poster doesn't give name or bike details, I 'thought' it was a K12S (or is the username just a ploy to confuse us all?) and I 'thought' the hot start issue was a K13 problem!
I also 'thought' the hot start issue was a 'cranking/starting' issue, not a 'dead bike' issue, which is what the OP is reporting; no dash lights, nothing!
If my dimwit assumptions above are all correct, I would suspect the immobiliser ring antenna might be starting to go hay-wire. When they go, the bike never lights up as the ecu never gets the OK from the transmitter in the key. This was (and as a legacy, still is) why I bought and always carry a spare ring antenna
Actually, having just re-read the details of the faulty antenna symptoms, the bike 'might' light up but you get the EWS warning on the dash.
Either way, it needs to head to a friendly GS-911 owner (who we could direct you to, if we knew where you lived!) or a dealer. The GS-911 might not help as the ring antenna only throws a fault code about 50% of the time.
I have reported similar intermittent problems with my K13S but have never noticed, in my frustration hitting the starter and cycling the ignition, whether my dash stays dark or lights up and hopefully I never find out.
