Doesn't seem reasonable to me.
Your description is of an airplane going from just below stall speed to an airspeed that could damage the aircraft before the pilot is able to regain control. I don't think a "high-speed dive" could explain that. Once you're in a dive it should be pretty easy to get the nose up.
Going into something like a flat spin may be a possibility; I have no idea on how vulnerable airliners are to unrecoverable spins.
