Y wife has a 98 honda accord.and of recent while she is driving it shut"s off and she also noticed it does this too while accelerating or decelerating and or making any sudden movement,she usually turns the ignition off and shift to park before attempting to restart,and it does so readily anyone with a similar problem or a solution please feel free to share your knowledge.

Test/replace the ignitor and coil. AutoZone will test these components for free. Likely, it a bad ignitor.
