I have a 2012 s250. Driving across the yard not working it and it suddenly stopped dead and no hydraulics. I can shut the engine down and restart it and it will work for about a minute then shuts down again. My first thoughts were the sensor for the safety bar but I put a jumper wire in and didn't help. The light for the safety bar comes on when I put it down . When it shuts down the lights on the left panel are all flashing. Can anyone tell me what I'm dealing with?
