We have a 1988 35 foot Luhrs Alura with twin chrysler 360s in it. They start up usually and run and sound like champs. But after about a half hour usually or more they sound like theyre gasping or something for about a minute then they shut off and don't start. We were in 4 foot following seas when this happened once, that was fun. They are carbuerated. We also replaced the solenoids on one or maybe both. We installed a fuel water separator, flushed the tanks out, and even emptied one. We belive the previous owner put water in the gas tank because it had the water tank lid on it:facepalm: We had both carbs cleaned and rebuilt too. We tried everything, any ideas?
