To break up like that I'm going to suggest the V rod bearing has a fatigue failure due to engine speed - note that the inertia forces increase with the square of the increase in engine speed, so double the engine speed means the inertia forces are four times higher.
Once the V bearing has gone then oil pressure is lost to the crankpin and the H bearing is starved of oil.
