System shutting down

start

#1

intermittently the radio screen will display “VEHICLE FAULT: SYSTEM SHUTTING DOWN”. Then teh NAV, AC, Radio, and digital part of dash shuts down while the car still drive. The flashers come on at this time. If the car is shut of during this time it will not restart ofr 15 to 45 mins. Seems like securioty system related. The BeCm has been reflashed, which curred the problem most of the time but after using remote locking system problem returned.

Any answers on how to resolve
