Ignition Switch problems of the 1997 Acura Integra

1997 Acura Integra stalls without warning. This has happened on 5 occassions, twice on the freeway. The vehicle starts immediately after the stall. I checked the manufacturer recall list but this vehicle was only recalled by the malaysian doh and not by american Honda. It was manufactured during the 1996 to 1999 recall timeframe for the recall to apply to this vehicle.
