I have a 2003 scag turf tiger. I was running it today and the right hand pump on the mower glitched and stop working for 5 seconds, then came right back on. i kept mowing and then bout 10 min later it quit started whining again real bad and it quit moving on that side. So i stopped and looked at it. couldn't see anything wrong so i jumped back on and it started working again for a couple mins. then stopped again. got it to the trailer and parked it. finished mowing with the other mower. got to the trailer again and it was working. then stopped again. Does anyone know what would be wrong with this pump? Its a BDP-16A-307 pump.
