My dashboard was acting weird. Parked car, and now won't start? Why? on 2004 Kia Sorento

Happened around 10:53am. The problem just started. The lights on the dashboard were acting weird and flickering. When I parked to do a quick errand, and came back to leave the car would not start.

Might be the wiring harness, had to replace mine a few months ago....
