Electrical problems can be some of the trickiest issues when it comes to car diagnostics. However, there are only a few potential problems that can cause a car’s electrical system to completely fail and then suddenly work again.
6 Reasons Why Your Car Loses Power Completely and How to Fix It
If you haven't done any diagnostics yet and you're comfortable checking a few basic things, a good place to start is with the car battery.
Loose battery connections can cause an electrical system to "shut down" and then start working again, just like bad fuses. Therefore, the connections between the battery and the rest of the electrical system should be thoroughly checked before anything else happens.
In addition, a problem with the ignition switch can also cause these types of problems. If the problem is deeper, the vehicle will likely need to be looked at by a professional.
