I have a 2012 550 eps touring that failed to start on 3 separate occasions. the first 2 times I turned on the key and the fuel pump would not activate and thus would not start. each time after about 2 hours of sitting the machine would go back to normal and start. the third time I had the same problem with the pump not activating and also lost power to my grip warmers and winch. the dash also showed a problem with the eps. I trailered the machine home and this morning everything is back to normal. the problems all happened after riding to my ice shack and sitting for a few hours. any ideas?
