[s-cars] Died on I4, now no-start

[K.C. Madsen]

Driving along at about 70mph, everything seemed fine.  Suddenly and with 
no warning, RPMS dropped like a rock and car dies.  I coasted to a stop 
on the shoulder.  Car refused to start.  I turned the key and heard 
nothing.  No cranking... nada.
I'm trying to figure out what could cause the car to die while happily 
curising at 70 and also keep it from turning over...
I had it towed 130 miles to my mechanic (who I'm getting to know better 
and better).  Perhaps it's something simple I can fix on my own before 
he gets to it??
