If the pump stops or sucks air, I would assume that they ALL starve simultaneously well except maybe for the one with the most clearance. As for which one destructs itself first, IDK.
That said, I have had two 340s go down at the #1 rod, at ~6000rpm. The mains were just fine. After the Second one went down, many years later; I researched the why of it, and my 360 has had no problems.
