So I was driving last night and was going about 45 mph onto an off ramp and then my car proceeded to shut off, lights and radio were still on as I remember. Cranked the key and it started back up and I drove it about the 5 miles it was back home with no problems. Took it to autozone today and alternator and battery both tested good. Any thoughts, was it maybe just a one time thing possibly? Btw I checked fuses and battery and nothing was loose.
