    I have a problem with fuel supply, looking for a schematic of the fuel system, tank location, access, etc.
    After running motor and stopping for a while the fuel drains from the fuel pump, motor will start and run a little on the fuel left in the carb than stall, have to crank the motor for a long time to get the fuel back up to the carb. replaced fuel pump, filter and rebuilt carb, might be a vapor lock, I insulated the supply line but didnt help. Does generator draw fuel from the starboard motor? fuel line?

    Sounds like ethanol has done its work .. Find the fuel pickup from the fuel tank .. There should be a couple of one way valves at that location and they may be clogged ... Mine had a jelly like substance clogging the one way valves ... I removed the substance .. And it happened again the following week but never again .. Run stabilizer with EVERY fill up.

    well I replaced the anti syphon valve, checked all the fittings from the fuel pump to the carb, checked the fuel filter and connections, the motor started great ran at idle and thru full throttle range , late idle for about 30 minutes and than it lost fuel and stalled,

    sounds to me like I have a bad fule pump but would it work sometimes and than not work than work again?

    I'd look at the air vent to make sure you're vent isn't clogged up first. How full are your tanks ?

    If the problem comes back in the next few trips, you will know the problem was ethanol and like me, you will never again fuel the boat without adding the stabilizer fluid.
