Cut out while warming up now won’t restart

Hi guys, I took my f4 out of the garage today and whilst putting my helmet and gloves on I started the bike to warm up a bit, it Sat happily ticking over for about a minute and then just died, it didn’t stutter or stumble it just shut off dead, all the dash lights were still on, so I pressed the starter button, nothing! Switched it off and back on again and tried again but no luck either, my first thought was a fuse so stripped the fairings off and checked all the fuses on the right and the 40 on the left, but they were all good! I also notice now when switching the ignition on the fuel pump doesn’t seem to prime like it used to either?? Am I missing something or has anyone experienced a similar thing??
