While driving the van the lights on the dash board goes out. The speed declines slightly, and the headlights blink on and off. The radio turns on and off. The heat turns on and off. The alarms inside starts to chime. The power is lost to the windows and the door locks. When driving at night the dash lights go off and when this happens you cannot see the speedometer or anything else for that matter. This really needs to be looked into. I'm afraid that this electrical problem will soon cause a fire of some sort.
