Lost 97% electrical inside and out after parked for one hour?

Basically, everything stopped working at once except for power door locks, door courtesy lights, hazards, and flashing security light on dash. No headlights, blinkers, taillights back up, brake lights, no radio, no wipers, no power windows, no dash lights no gauges no meters no temperature, no clock, no dome no vanity lights, no horn, no lighter, no front or rear A/C or heater, no sunroof, no rear window and so on. Car starts, runs, drives and shifts as it should but recently feels a little hesitant at random times. Almost like sputters between 20 MPH to 40 MPH.
