Seems like it started when I got the pathfinder back from the radiator/transmission replacement. The radio looks dead to the eye, but if you shade the power button, you can tell it's getting power for half a second, then off. I thought the radio went shot, so I replaced it with a nicer Dual Din unit from Crutchfield. It did it again this week. Everything is stock as far as wiring, used the Crutchfield harness and made good connections. If it keeps up, I'm going to end up rerunning power and ground.
Anyone have a better idea?
