Boat was running fine for an hour under a surf load. Was switching over to a goofy rider when all of a sudden boat started to spit and sputter. Gave throttle and stalled out. Sat around had some lunch, opened the sun deck to cool engine and blower on. After 1/2 of sitting around fired up ran fine for 1/2 hr than the same thing happened. Limped it off the water put new fuel in it, let it sit overnight and than put it back on water next day. Ran fine. Was it bad gas? Or start of fuel pump/filter tiring?
