2008 Ford Escape Hybrid Q&A

2008 Ford Escape Hybrid Question: Beep, then "stop safely now" appears in mileage window, then black.

This happened on the freeway after driving about 20 minutes outside it was dry and about 60 degrees F. After I safely coasted to the shoulder and cried a little, it started back up with no indication it had gone dead. Is this a sign of something bad? -
