Sorry for the novel, wanted to be thorough. 10 hrs on Rebuilt power head, engine recently started shutting down out of blue on the water. No Sputtering, beeps or other warning. Has done it after 1 min on water following 5 min warmup in dock; also did it yesterday when it ran fine for 25 min on water, then we anchored for an hour, then it shut down 30 seconds after we pulled anchor and headed out. It won’t start, just turns over as if the kill switch was on. Restarts after sitting for a few minutes. Thought it might be overheating until yesterday when it did it after anchoring for an hour. Please help!
