I was driving down the road maybe 30-40 mph and nothing was acting up, then all the sudden all of the tires lock up and almost throws me off. The engine was still running but I turned it off after I stopped because I couldn't hear it running because while the tires were locked up it was skidding on rocks and it was so loud. I did a quick look around, nothing was smoking or leaking. And when I pushed it off to the side of the road it was still locked up. I walk about 5 miles back to my house, grabbed my friend and my truck so we could tow it. We got there and we had to turn it around, so we turn the wheels and try to push it then the tires weren't locked up anymore, we decided to turn it on and try to drive it and it drove fine. We drove it slowly up to the house and there was no issues with it. I'm so confused right now, could anyone help? I would like to fix this before I use it again because I don't want to be going 50-60 and that happen again because it would more than likely throw me off and possibly hit me if it's still trying to stop.
