98 34' Allegro - Chevrolet - Runs great and then just dies

Just another thought, but the fuel line in the tank may be cracked and sucks air when the fuel in the tank sloshes. Had that happen on a Harley once. Bike ran great as long as the tank was full, but after it got down to about a half-tank and it sloshed approaching a stop or leaning on a hard curve, it cut off. Turns out the fuel line in the tank was cracked and when the fuel sloshed and uncovered the cracked line, it sucked air and killed the engine. Full tank, the crack stayed submerged and ran like a charm.
