No, a plane gets increased control in a dive because there is increased airflow over the wings and control surfaces. Your range drops because you will be descending faster to get that airflow. Control is lost when the plane slows down too much because the pilot is attempting to get more range with a flight profile closer to level.

Once airflow over the wings slows down to the point that the lift is no longer greater than the weight of the airplane, it stalls. An airplane can stall with the engine running just fine.
