2006 Scrambler 500 H.O. No Power

I have a @006 Scrambler 500, I was riding it and out of nowhere just lost all Power. It just turned off. I get no power to the Key switch. I have searched up and down. there are no Fuses, or circuit breakers anywhere. I am not sure if they are inside the ECM. can anyone help me with this issue. Id like to get back out riding before the summer is over.
