Random loss of power

Iíll be cruising along and all of the sudden the motor will just turn off but the lights on the dash and the headlight are still on. When it happens I pull the clutch in and press the start button and it starts up. Then itíll run fine after that. It did it three days in a row. Ran good for two days then did it again today. Has this happened to anyone else?

Sounds like you're losing power momentarily between the battery and the igniter box, essentially flipping the kill switch.
The ignition puck itself is a common source of problems similar to this. If a contact starts going bad it can break the circuit. You can either buy a new one, or open the old one up to clean and tighten up the contacts. There are a couple threads with instructions around.

Could it be something silly like a loose ground wire?

Another vote on the switch, but be mindful of the wires going into the switch as well. If you clean and reassemble the switch, start the bike and try shaking and twisting the switch wires to see if there are any breaks.
