It just died, what would cause that?
 

Rolling along about 25, card just dies, Sounded like the radio went out too but not sure-coasted to a stop, cranked it a few times no go. Got a push out of the way, cranked it up and it started right away and made it a few miles home.

560 sl, good cap, good rotor, recent plugs.

Loose coil wire maybe? New wires needed? What?

have ur alternator checked. if that is fine then the battery is next. while u're at it double check your battery terminals as well for corrosion.
good luck !
