Johnson 6 hp outboard stalling...

Greetings all, This might sound like a puny issue to most here, but it's got me stumped. Here's the scenario...... 1976 Johnson 6 hp, 12' V-bottom boat, new gas tank, new fuel hose. This lil rascal runs and starts fine for the most part, usually 2nd pull after choking it cold. Push's this boat along great on the small river we are on. It could be hours, or could be minutes, but invarily, it will stall, and die. Just up and quit running. Then I'd say 50% of the time it'll restart on the first pull, and the other 50% it'll take up to, say, a half hour to restart. I've learned to just let it set for awhile, set back and enjoy the scenery, and eventually it DOES start again. I've had the motor looked over this spring, new impeller, (pumps PLENTY water), carb cleaned, new plugs, and timing set. I've checked the hoses on the motor for fuel leaks, cleaned the fuel filter, and I've always run the correct fuel mixture. Any ideas at what I might look at? I'm not above taking it back to my dealer, he's been great to me over the years, but thought there may be something simple I'm overlooking, or that someone could suggest what it could be so I could possibly pass along to the shop. TIA

The new fuel line is my first suspect - is it a Tempo brand?

My guesses. first, some sort of loose connection in the ignition system that opens up, or something in a kill switch that takes down the motor. Second guess is something that once in a while causese the prime to be lost in the fuel line. Del

Air leak or weak fuel pump is what it sounds like until you say it will not restart, I assume even with priming and/or choking. Check for spark the next time it happens.

1976 was the last year for breaker-point ignition, check points lately?

Dirt in fuel bowl will cause these symptoms erratically, too, intermittently blocking jets.
