I've had this problem twice within the last month. while I was driving, all my gauges shut off but the car kept running. i pulled over turned the car off and tried turning it back on. it didn't work. so I replaced the battery, starter, and alternator. problem was fixed untill a day ago. car did the same thing. I've checked the fuses but none of them look burnt
