Her is a stumper for me. My Genset has always been very reliable. However, today, it shut down suddenly. It restarted after a few moments, and ran for a short time, and shut again. Surges when first starting and then smooths out. I checked fuses, and also connections. Plenty of water flow out the exhaust. I tried a spray of gas from a spray bottle to restart but crank and then no start. I have replaced the capacitor last year, and again, no issues. Changed the gas filter. I use a Quick Silver 35-802893Q01, so plenty of capacity. Voltage at 120. It just cuts out and dies.

I had marina replace the anti siphon fitting over the winter just because it was 26 years old. Happened whether on aft tank or main, although I believe it only draws off of port tank. nines run fine. It just died after 6 minutes of run, and restarted like nothing happened. Any ideas???
