Why are ALL the warning lights coming on while I am driving?

Have a 2009 Dodge Grand Caravan SXT. While driving all the warning lights come on, the windshield wipers come on, the cd and dvd player don't work. After this happens the automatic doors do not work(sometimes). The problem seems to come and go. It started while driving across country about two months ago. It had been ok for the past few weeks then last night it started again.
