My first thought is a bad battery or alternator. You could also have a failing body control module. 5 Common Symptoms of a Failing Body Control Module (BCM) - Module Experts

Trying cleaning the battery connections. Then check for power getting to the fuses in the panel under the hood. If that is okay then move on to the ignition switch and fuse panel in the dash.
