A possible charging system problem. If the alternator fails to maintain the correct charging rate the BCM could disable consumers to conserve energy so the engine could run.
Take it to a repair shop and ask for a charging system test, ask them to do it after a few miles of test drive while the consumers are on, i.e. radio, lights, A/C..
