I know that on most vehicles, regardless of make, they have a main power wire that feeds everything you describe.
As mentioned before me, they typically have a fusible link.
About ten years ago I had the identical symptoms in my old pickup.
I traced my wiring and found a corroded connection on the main power feed wire. Not the battery cable, but a secondary large wire that went through the dash to feed the items you describe.
I suggest tracing that power wire with a test probe until you find the "dead" spot
