Ok, I was on my way to the SDAC-Chicago meeting today in my 87 CSX when all of a sudden the car lost all spark and fuel. As the car slowed to around 30mph, the engine fired back up after a loud backfire and continued to drive. This loss became frequent enough that I turned around and headed back home, but it got so worse that I would have to let the car sit on the side of the road before it would fire back up.
Any ideas? I'm thinking it might be the HEP.
Oh yeah, no codes and the check engine light operated normally when the motor wouldn't run.
