engine dies like i turned ignition off, only i didnt.

What is your question?

driving down road at 70mph, engine dies, everything on the dash shuts off like i had turned the key off, then it will come back on, no check engine light or anything. if it stays off long enough for me to stop, it will start right up when i turn the key, but once i turned the key and nothing happened, no starter, no dash lights, nothing. kept trying, and it finally started.
