Corroded connection somewhere.
Loose plug
Faulty fusible link, fuse
A small animal chewed something

Look at a wiring diagram and use a high-lighter to trace all the affected circuits. Look for a common point of failure. Use a test light to make sure you are getting power to all the affected circuits.
