While driving, I will loose all electrical power causing everything to go dead including the engine, radio, door locks, windows, etc. What could be the causes and how do I test to verify?

Hello Rob, Make sure your battery cables are clean & tight, also your ground cable to engine & your engine to body ground. After that I would suspect the ignition switch on the steering column. If you have the column with plastic cover top & bottom, remove the bottom cover (3 torx or philips screws) & with engine running wiggle the wires going to switch under the key. You may also duplicate problem by wriggling the ign key with engine running.
Good luck Sir,
Billybob
