Hey Brad!
So you're saying that there seems to be a relation between the headlights and the engine issue... Seems strange, but I've seen similar symptoms on a car where one of the clamps on the battery poles weren't secured tight enough (even though they did look/feel ok). Could also be that the ground wire (running from the negative pole on the battery) has a bad connection. Check and clean those first, it's both easy and cheap.
If it's not related to the battery you might have a faulty sensor somewhere. If so you should check your onboard diagnostic sensor for any codes.
Good luck mate!

there's a roll pin that goes thru the drive gear.I'd change the ignition coil before the pick-up coil, if the pick up goes you'd be lucky if it would run above idle.if it has no power when it does run, try the ignition coil first.
