so heres the story

take the car out because my truck was being used today by my dad. I'm driving home from school and stop at a red light when my car mysteriously shuts off. It turns over but doesn't attempt to start. It has to be a spark problem I believe. So I push the car over to the side of the road, check the plugs and plug wires and everything seems fine.

My car is running an MSD digital 6, which has an led light that stays on while the ignition is on. ONe of my questions, esp. to Mike K since I know he has this exact same ignition, is that light on when the key is in the "on position but the cxar isn't running. Then I have narrowed it back down to the MSD box. This will be the second one that goes bad on me
