Let's be really clear on what is and is not happening.
From what you've written above:
1) Bike was working fine, left for a short period, nothing has happened to it between it running and not, however trivial.
2) The bike turns on with the ignition and display lights up, fuel pump can be heard to prime.
3) The bike turns over strongly on the button
4) There is a spark from both plugs when removed and grounded against a good earth.
5) The bike does not splutter, cough or smell of fuel.
6) The headlights have both blown.
7) There are no errors shown on the dash when the bike is turning over or before the starter button is pressed.
Does all of the above sound correct, or is anything not as above?
More importantly, were you able to find another way to get to that date?
