Did you pull codes? Do you have a 2.4 or a 3.3l engine? As I understand your post, car is not cranking but you're doing all your screens go black. When you so trying to crank it, door the screens come back on? It could be a loose battery terminal, make sure they're tight. Could still be a wiring issue; jostling the vehicle could cause to opens ends of a wire to make connection. Does car cut out while driving?
