Electricity cutting out

As I drove home yesterday, I noticed the radio cutting out and in. And then noticed the spedometer’s needle and other needles flicking down. It only lasted for a second then returned to normal and repeated a few times. It was a short time home and then when turned car on a few minutes later, it was fine and didn’t repeat.

Any thoughts?

I would suspect a intermittent problem with the ignition switch first. Try turning the key back and forth slightly when the trouble happens again to see if that has any effect on the trouble.
