I am working on an 85 ski nautique for a friend he said it had some stalling issues. He bought a brand new holley for it from PCM this is where I got involved I swapped the carb for him drained the fuel tank and installed a new wix filter in the fuel water seperator and new sparkplugs. I put the fake-a-lake on it and started it, it ran great in the garage. We took it to the lake it started right up got past the no wake zone and throttled up. It responded great then died. It restarted with no more than a turn of the key ran fine for a minute then died the same way. I pulled the flame arrestor off and pumped the throttle fuel shot out of both boosters we restarted it and ran it for 20 minutes after that with no issue at all. The next time out he had the same problem. I was wanting to try to get some ideas on were to start when I go help him again. I really don't feel he has a fuel problem because of the way it died like a switch was shut off then restarted without a hitch no cranking to refill the fuel bowls. It never sputtered it just died. Any suggestions would be greatly appreciated.
