I did have an ignition switch replaced. The truck very intermittently when off and parked loses electrical maybe brain. No electrical comes on . tonight came to driveway to pull in garage no electrical. Went in house waited 20 minutes turned over dash lights came on but went back off. Waited a minute all electrical came on turned over started. It has never died while driving. Also will not come out of park apparently the switch has no signal when button pressed in. Any thoughts
