Question about 2003 Yamaha YZ 250
Check the chassis wiring whe it enters the side cover on the ignition side of the engine. There is supposed to be a rubber grommet there. Soetimes that grommet gets kicked loose where is comes out of the side cover hole and the wires chafe to the point that they ground out the ignition module.
Also looks for bare wires under the gas tank around the ignition coil module. Everything your describing points to a chassis short to ground.
Also the problem can be in the handle grip with the kill switch or a bad kill switch.
It is probably time to break out the Ohm meter and start chasing wires.
