I was driving on the freeway when my engine just totally shut off. It didn't choke or anything. It just shut off like I turned my key off or something. I pulled over and cranked it and it would start for 1 second and die out. After 30 minutes it started and I was driving normal again.

I'm scared to drive it now. Anyone have any thoughts on what it could be?

93 civic si hatch - has a new distributor cap and rotor.

 

possibly be main relay!!!?
