Radio and power door lock problem

Got a problem that makes no sense to me.

Randomly the radio and power door locks will lose power then randomly power returns.

When the power returns the radio clock doesn't know what time it is but if I turn the radio on it still remembers the pre-set stations. The power locks will not work with the switch or FOB. Noticed this AM that the headlight ON warning tone does not sound if I leave the headlights on and exit the truck.

Headlights, tail lights, power windows, horn, wipers, interior lights all work normally.

2010 4X4 Sport with 4.0ltr

Any suggestions? Where can I find a wiring diagram to start trouble shooting?


Instrument panel lights and headlights do now operate during the random power loss.
