Sounds like you have two issues.
Lights are normally 12 volt DC. Is the light between the table and chair in a slide out? Check wiring to see if it is pulled a part. Is the light bulb(s) good?
Receptacles are 120 volts AC. You have lost power. Do you have a large inverter? Check for small white or red reset if you do.
Are you connected to shore power using an adpater? What type of service?
Cycle breakers.
Turn off all breakers applying light pressure toward off. Turn main breaker on, turn on branch breakers one at a time.
Do you have a plug in circuit analyzer? Get one.
