While driving my 93 s-10 Blazer, everything turned off. Now it has no electricity at all. I was driving, made a left turn, drove about a quarter mile, then the engine stopped, lights went out; it is as thought my battery were disconnected all of the sudden but my battery is fine. What could cause a sudden loss of the entire electrical system?

Welcome to the forum, Are you still having the problem? I'd have to make sure the battery has a full charge and all connections are good on both ends. If you have a junction box, with fusible links, check there also.

Yes, I have checked the battery at both ends, and removed the main fuses but they are OK. Where do I look next?

Did you use a testlite on the fuse circuit? Even if the fuse is good, if no voltage on the circuit, the circuit is still dead. Just pick one circuit that is dead and backtrack the circuit. Some fuse circuits are hot all the time, some go hot when you turn on the key.
