Just bought the rzr last weekend. I've only driven it a few miles but sometimes in high and coming to a stop the engine dies. It starts right up in park but when shifting gears it lounges and kills the engine. Like the clutches are stuck. Also driving first time at high speed, it would max out at 48 mph. Sometimes it would almost bounce or lounge back and forth. Then it let loose like it hit another gear and shot right up to 70 before letting off. Let slowing to a stop it would die again. Hope someone can make light of this. Thanks in advance.
