I had the same problem called the dealer but they could not get it in. The service tech said what happens a lot is the battery voltage gets low and when the starter kicks out it gets hung up on a tooth of the flywheel, He said to put a wrench on the end of the crank on the engine and work it back and forth and is should break loose. It is a tight fit to get to it but i did that and it came free, It took a bit of time to get it free, Just had to keep working it back and forth, Never had it happen again but saved me from not have a gen for a long trip. I believe it was a 17 or 19 MM wrench that was needed. Hope this helps.
