I've lost two Time Atacs the same way. The pedal came off of the spindle, once on a local ride and the other at the USARA Nationals.
That's what's happened with the Eggbeaters... remember when you replaced my left pedal with a flat pedal at the last Rage? How long did you have your Time Atacs before they did that? What do you use now?
The one that went the last time was only a year old. I just switched to Eggbeaters. :) I forgot that the one that i replaced at the Rage was an Eggbeater. Oh well. We will see what happens.
