Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

On startup this spring the engine started immediately and ran at idle. When I launched 10 days ago engine started and ran but after leaving at trailer launch engine died. It restarted but continued to die after a short time but I was able to make it to my slip. Now every time I start it runs and even accelerates smoothly to 1400 or even 2000+ but every time, after a minute or even two of running smoothly, the engine cuts out.

Mechanic's Assistant: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the Marine Mechanic should know?

I have changed the two water separating filters, changed the inline filter, changed out the oil pressure switch which powers the fuel pump and I still have this problem. Any thoughts?
