I have a 2005 Ranger, 4X4, 4.0, automatic. New problem this week is that when you fire up in the morning (or anytime) turn on some tunes, and everything s just fine except when you put the truck in gear and the radio goes off. Put it in Neutral or park and the radio works fine. Put it in any gear or park and off she goes again. No recent work done to the truck or radio.
