Elerctrcal problem

msmith54

I have a 1999 Plymouth Grand voyager. Runs great!, but he accessories tend to shut off. Radio, wipers, windows, locks. If I stop and restart they're back. Some times all day, sometimes 20mins. I called the dealer and asked if this was a common problem. No. I got check for mice, or nibbles on the wiring I'm thinking ignition switch. It's only the accessories but it's still a nuisance.
