Ok that probably rules out the pump.

Take the coast guard approved check valve elbows out of the fuel tanks and try that.

How is your fuel pressure?  Can you verify if the carb has fuel in it just after the engine stalls by looking at the accelerator pump shot?  Do not crank the engine or actuate the throttle until you can look down the carb.

What electronic distributor?  Were any of the original ignition parts reused?  Try duplicating the problem wow you have a timing light installed.  Watch the timing light to see if it stops flashing just before the engine stalls.

Fuel pressure is about 6.5. And there is fuel in the accelerator pumps. Also i have been unable to duplicate the problem on a trailer. There are no og ignition parts. Ive replace the key, coil, plugs, distributor.

That or you may have an Eletrical\ignition issue??

But the motor doesnt just stop it feels like its running outa gas and if i play with the throttle when it starts to cut out sometimes it keeps running.

Check the roll pin in your distributor drive gear

Sounds like everyone is on the right track.  Check all previously stated to rule out/troubleshoot. 

Wear ring worn out feels like tranny slip in ur truck

The ignition has been touched so could be issue but sounds like fuel is getting weak flow.  How old are ur tanks are they clean free off debris.  The checks are usually the suspect and should be removed from pick up tubes as someone mentioned. 

I had fiberglass tanks found out the hard way about replacing the entire fuel system. I would have clean carb run great a whole weekend next time out clog or restrict carb.  Fixed it I had got new tanks larger lines (no checks) larger pick ups. 

Fuel and fire your fire sounds new

The tanks are original but are alum. Also before I started to rebuild the boat i cleaned and flushed both tanks. As for the checks how do i remove them they look to be welded into the tank. thanks four all the help.

Low voltage to the coil/ ignition. I had it happen to my sw 18 changed everything. Ended up being that

Is there a way to check the voltage while running the boat? Also, if it was electrical wouldn't the boat die instantly and not feel like is running out of gas?

how do i do that. the seem to be welded in if i remember correctly

My friend just got over this same problem this past weekend!! He pulled and checked carb, all good. He then contacted Mallory and they said change out the coil, he did that, same problem!

It ended up being the wiring to the distributor and coil having bad ends that he couldn't see through the heat shrink tubing. All his time and frustration over a couple $0.10 wiring connectors!
