Electrical truck just died on me. on 1997 Toyota 4Runner

When I was driving I heard a loud snap noise and my doors unlocked my radio turned off. When I got to my destination and turned off the truck I restarted it to move it and it's dead. No noise..nothing. It just died on me. Could you give me any idea what could have happened? I'm not near my mechanic because I'm traveling..please help a.s.a.p. This has never happened before..

Best guess=blown fuse. One of them big fuses called a maxi fuse. Just a guess.
