I have an Evinrude Etec 200 HO a model #E200DHLIS Serial #05277819. I had problems today with my motor shutting off at wot. Did this 3 or 4 times. Was still doing this when I came in. It will start right back up and you can idle down the lake just fine. When you are running at wide open throttle it just shuts off. No warning buzzer or anything. Ran fine this morning. Any ideas?
