The LCD clock going dead pretty much precludes the problem from being
in the ignition switch. If the main fuse wasn't carrying any current,
the bike could still run off the alternator output. Make sure the
battery cables are tight not just at the battery but where they connect
to the starter solenoid/main fuse and also where the negative cable
attaches to the frame.
I would start by checking the integrity of the main fuse socket and the
associated wiring. Wiggle stuff vigorously, it can be helpful to attach
an audible or visual indicator to some point in the wiring harness so you
know when you've started wiggling near the broken wire/bad connection
without having to be looking at the dashboard, etc.
It's also possible that the battery may have an intermittent internal
open circuit, it's rare but has been known to happen.
