So I’m pretty mechanical, but this one is getting me. 115 Mercury efi 4 stroke. It fires right up, idles fine, gets on plane, may run for 5min or 1min, but then cuts out. I can go back to idle for a minute and same thing, gets on plane and then at some point cuts out.

I’m leaning towards fuel pump or coils going bad. I’ve changed spark plugs, fuel, filters, had the injectors cleaned.
