Ok so I have had some extremely weird issues with my Z.
Ill start with it has a new alternator, rad, clutch, rear dif, all brakes, and new battery.
Its all started one day after a small rock chip happened on the windshield. (Im positive tha has nothing to do with the issues but its funny to think that the car gave up hope afyer losing its good looks)
So the car was still driving fine but most of my interior lights would turn off intermitently. But the dash lights would stay on! Car was still driving fine at this point. Then one night driving home I went to turn on my high beams, and as I flicked the switch, ALL the cars light would turn off!! No dash lights or interior lights of any kind, and NO exterior lights of any kind!. As soon as I flicked the high beams off, all other lights would resume as normal. Car was still running fine at this point.
The next week while driving to work, car seemed as though it was starving for fuel, I turned all electrical stuff off (music, heat, wipers, lights) and it improved a bit but as I pulled in oy stall, the car died. Started up fine but sputtered and died again. I went to work and came out on my lunch break. Car started and idled fine! Got it home after work and same issue of dying. Charhed the battery and pullednit into my driveway and now I don't know what to do!!

Please any help would be greatly appreciated!!
