The condition you experienced was over cooling. Boats are water cooled but they aren't over cooled. Generally they need to reduced water flow in very cold conditions to get the engine up to normal operating temperatures. Diving through several hundred feet at idle with a diesel can over cool it and it might miss for while until it warms up after opening the throttle. I've experienced it before. I think glow would have kept running as long as you didn't take off lean.
