I’ve got 2014 Viking with 13,000 miles on the clock. I live on an island and only use it to gather provisions. My problem started about a week ago, I turned it off, ran an errand, came back turned the key and nothing. Lights on the dash came on, but it didn’t try to crank at all. I put it in high gear and rocked a time or two and it fired right up. It’s done this a couple of times since, but not consistently. Any ideas??
