Try hooking a jumper wire from the battery to the starter by-passing the relay. If the starter cranks ya got a bad relay. OR, there's a problem with the hot wire to the ignition switch and the relay. That would explain the sudden shut down.

Just because you read 12v does not mean anything, what does the voltage do to when you hit the start button.

Switch the starter relay with the brake relay and see what happens.

12v is a discharged battery ... should read 12.7v across the terminals , makes a difference . Charge the battery up to get the engine running then put the voltmeter across the battery terminals and measure the volts , should read more volts when running than when off and increase when you rev the engine . If not then the charging system is at fault .

Agreed. Battery is either bad internally, or the charging system (Stator/regulator) took a poop on you.

Charge batery and load test.

Test stator.

Test regulator.

Take the VR plug out of the stator. Put a meter on the output of the stator, with the bike running check for 32V AC (not DC) at 2K rpm you should get 32 volts AC. If that is good, connect the VR and go to the battery, you should be getting 14.7 or so volts DC from + to frame ground. If not it is probably the VR, maybe the battery, less likely though.
