Suzuki King Quad Through Ice

I have a 05 king quad 700 that runs fine when its cold. When it heats up high and reverse wont show up on the display and high will go to 15 mph then bog down.. Any ideas?

1700 miles on the machine, all trail riding.   Second ride of the day and I get an overhead light, shut it down, let fan run, fan shuts off, light still on, ride back to camp, clean radiator, let machine cool for a couple hours.  Start up, head over to the campgrounds, ride for 5 minutes or less, overheat light comes back on and the machine blows the ignition fuse.  Tow it back, replace fuse, turn on key, fuse blows immediately.  I've ran all the wires, no mouse chews or rubbing, etc.     Does the KingQuad have a thermal protection system that would explain this?   

I am not sure what is wrong with my King Quad. I had a new carburetor put in 6 months ago, just replaced the fuel pump and added an in-line fuel filter in. I have been trying to fix this quad for a while now and do not know what is wrong with it. It idles fine and runs great as soon as it is fired up, you can Rev it and stay in first gear with 100% power. As soon as I drive 10 feet it looses all power, I mean it is sputtering and doesn't move at all, but when I let off the gas after it sputters it idles fine. I will attach a video of what it is doing.

While cruising, my 2011 750 king quad suddenly shut down. As it happened, red lights on the display flashed. Any ideas? My head lights suddenly stopped working about a week ago, if that helps. I have no power at all. Thanks 

Looking for the rectifier.  Most bikes have near magneto.  It appears the KQ has it in front.
Can someone tell me exactly where it is? 
Bike not charging and magneto checks out ok
