I went down to chadwick mo for some snowy riding. Unloaded the quad and it was riding great. Drove around for at least 2 hours no problems. It got cold so we headed back to the truck and trailer. Only going about 15mph, then maybe 100' from the truck it dies. Like someone turned the key or switch off dies. Go to restart it and the motor spins really quick, no fire. Sounds like there is no compression at all. Popped the seat real quick and the spark plug was still in. There was no loud pop or crack or anything like that. Engine only has 25 hours on it. My dealership doesn't open til Tuesday morning. Any ideas?
