  Three on-off cycles in rapid succession is exactly what you get in non-urban electrical systems when a tree falls against a wire.

If there's still a short, it repeats, and after the third or fourth short->cutout (depending on the local utility settings), stays off on the assumption that the tree is well and truly hung up on the line and will need a crew to fix it. It's pretty common occurrence in many locales where I've lived.
