Not too happy about my two year old mower intermittently stopping while mowing.

Not too happy about my two year old mower intermittently stopping while mowing - and it's not an overload situation. It simply quits. It will start again once I (appear to) reset it by pushing the five sided key and also open and close the green side clasps on that lock the handle extensions in place. Been using a bungy cord wrapped around the handle and clasps to keep them closed tight, and this seems to have has helped. But not so much now and my warranty is running out. I'm told there is no service here in Fredericton, NB, Canada. Very disappointed. These are expensive mowers not to mention the two other EGO products I purchased only to find out I have no local service depot.
