Usually when they go like that if you don't have any funny sounds, knocks
or whatever, it's electrical.

You should check your generator and battery. If the brushes on the
generator are worn out, the gen won't be charging the battery and the
bike will start running off battery. Once battery voltage drops below
a certain threshold, the CDI units will stop firing.

Of course, it is always possible that a switch snapped, a wire broke,
or a CDI unit died. But check the simple stuff first.

It probably is an electrical problem, but one with a strange twist.
This machine has a generator that operates the CDI unit and it also has
a fuel shutoff solenoid on the carburetor. If the solenoid doesn't get
any power, the carburetor doesn't get any gas.

There are no brushes and the motorcycle has no battery. It's a
motocross bike.
