I love the thing but it is now giving us fits. For the last couple weeks I am finding that it will run strong but then miss a time or 2. I know all the issues with the floating fuel filter and I find the miss with a full tank also. Within the last few weeks it will run for a minute and then stop like I pushed the kill switch. Then it becomes a bear to start if at all for a while. I even replaced the $9.00 spark plug thinking it was bad. I cleaned the fuel filter which wasn't terrible either. I have it at the dealer now and after 2 days they called and said that they can't find anything wrong with it. He said they fire it up, blow the lot and it runs great. I am giving them a couple more days with it but I can see a 50.00 shop charge for nothing in my future and I know someting is not right with it. Anyone have any hints for me? Its 2 years old and probably has 100 hours on it. It has not had a valve adjustment. When it runs it is strong but the intermittent missing is troubling as well as the dead stopping. I have racked my brain and am leaning to an electrical issue but I don't know where to start.
