Thanks all! I've removed and cleaned both battery cables. (The negative was slightly corroded and not as tight as it could have been - not loose, couldn't rotate it by hand - but not tight.) Hopefully this does the trick. After reading some posts I originally thought it was the CPS or RCM. However, the posts didn't seem to match the complete loss of power - no power to any electronics either.

"This post is in response to the MANY occurrences of the "Mystery No Start" issue. Symptoms being car will die and/or will not restart but may restart after waiting for a while. Also, when attempting to start the engine all electronics work but the engine will not crank"

Also, I find it strange that popping the hood was enough to shake some life into the car. Seems more likely a bad connection issue then a sensor issue, but still strange none the less. You'd think hitting one of these Michigan potholes would cause the same affect. If it occurs again, CPS/RCM is next.
