Sounds like the battery went flat.

Who knows. Probably the hybrid drive system still has some issues to sort out.
On the radio they said it was going northbound so perhaps they already knew
about the problem and were trying to get it somewhere to sort it out but
didn't make it.

The circumstances (and some of the comments) are consistent with the
drive system becoming overloaded or overheated as a result of sustained
high speed.
