Just bought 2 waverunners (Used) and both appear to run fine, start up, idle, fast or slow, they seem fine. But the 2001 Polaris SLH (2 seater) will die ocasionally while riding it. Then starter wont turn over at all. Then you lift the seat and turn the battery key off then on again. Then it starts up. It does this many times randomly it appears. Its like the electrical system dies, we reset it and it starts right back up and will run for awhile and then it does it again. Anybody have a clue whats going on??
