The tanks in 33’s are baffled across (side to side) and reduce forward/backward movement of fuel. It may be that with the rolling momentum in the fuel shifted the top level below the take-up pipe even though it is in a recess well bottom mid aft of the tank. This lets air in, initially the engine can draw bubbles through with just a temp splutter but if a large enough air bubble ingresses, it stops. I found keeping the tanks well filled helped. If you can re- route to reduce the roll and suffer more pitch, or raise some mainsail to dampen the roll, that will get you home.
