If it's a sudden cut out with no warning I'd be thinking electrical problem too. If it cuts out again check if there is spark. If all the other electrics work but you have no spark you can focus on the ignition circuit. If you're losing spark on all four cylinders you can focus on points of the ignition circuit that are common to all four cylinders.
The components that are common to all four that are most likely to give trouble due to wear/dirt/corrosion are what the foccers above have suggested. The side stand, the kill switch and the ignition switch.
If the side stand is faulty the ignitor loses a ground so that would cause no spark on all four cylinders. If the kill switch is faulty the ignition coils lose 12V so no spark on all four. Those two circuits go through the ignition switch so if the ignition switch is faulty you lose spark on all four. And as fazerrider said check the wiring at the connectors going to the alarm. An open there would mean the ignitor loses the ground from the side stand so no spark on all four. You should check all those components and their wiring and connectors. If you have no spark on all four cylinders the problem is most likely in one of those areas.
A few other things that are less likely but would cause no spark on all four would be the pick-up coil failing, a problem at the cut-off relay, bad connection at the ignition fuse, failing ignitor.
