While anything is possible, the chances of a failed rod bearing or wrist pin are very low.........and, they wouldn't prevent the engine from restarting hot. I suppose that a ring could have fractured and one cylinder is now offline..........a compression check would find this quickly.

Unless one of the valves let go and dropped onto a piston, an improper valve adjustment..........or valves out of spec.........cannot cause the symptoms described.
