Put my boat (3.0L) in the garage for the winter last Oct. No fuel
stabilizer. 1/2 tank of gas.

Pulled it out periodically to start it...no problem.

Hadn't pulled it out since December so I pull it out a couple of weeks
ago and couldn't get it started. Fuel line to the fuel pump was dry.
No time to troubleshoot further so I stuck it back in the garage. Put
fuel stabilizer in at that point.

Pulled it put today. Sprayed carb-cleaner down the carb to give it a
kick.

It started up fine and ran very smooth.

Ran smooth for 5-10 minutes and then stopped dead. Won't start. It
will sputter if I spray carb cleaner in it, but it's not getting fuel.

What probably happened?

Thanks.
