I had an identical problem some years ago, and it turned out that the battey was apparently shorting out via some sort of debris in the electrolyte. It would be triggered by taking a quick turn or stopping shortly, which would agitate the battery and cause the entire electrical system to die (there was an ozone smell too, if I remember right) and you couldn't even jump star it. If you let it sit awhile, all returned to normal. I paid to have an alternator rebuilt, and it died on the way out of the mechanic's. I finally figured it out myself and replacing the battery did the trick. Maybe that's what you have...
