general problems of the 2002 Saturn SC

Have been having issues with the vehicle turning the ignition as it jams and at times fearful it may not turn next time I try to start it . . . . . But today while waiting at a red light. . . Car running, radio on and interior dash lights on. . . Everything just shut down. . . . The engine continued to run. . . But the rest of the car died. . . I was very nervous waiting for the light to change . . . . . Wondering if it would allow me to even get home. . . . Within in 2 minutes the electrical did come back. . . . I only purchased my Saturn in Feb, as used but did not start seeing these issues until the past 2 months. . . But have also noticed that this car model is not on any recall list with others displaying the same issues.
