I have a 2011 RGU, 11,000 miles, recently had cams, true duals, PCV and tune. Runs GREAT! On 2 occasions after brief stops, it has refused to start. Fob on belt, turn ignition and kill switch repeatedly. Engine lite usually does not come on, but sometimes comes on and off, but without whoosh of ready to start. Eventually started both times. So far only when engine is hot. I have an apt at local stealer for Julu 16. Any ideas as to what this could be?
