Has anyone had this problem: Too often when turning from one street to the next (going to the right or left) the engine abruptly dies and may stumble along and recover or may take me to the side of the road and then restarts and is fine. I do not remember this happening in a straight line even when I get on it to pass. I am really baffled. Perhaps the centrifugal force of the turn is causing something to happen. If I go real slow, it never happens. Any suggestions??
