While driving, the engine just died out. Tried restarting and it cranks up, but it won't start.

Sounds like the fuel pump failed, have a mechanic hook up a computer scanner and see what codes are present. The code will tell you what failed.
A defective fuel pump will rarely set any trouble codes but is a likely culprit for crank-no start conditions. You'll need to check fuel pressure. Try to listen for the fuel pump when you first key on (it will automatically shut off after a couple seconds). Also look for any blown fuses.
Had this happen two times. It was a hairline crack in the distributer both times, change it!
