Recently the car would not start.Checked,there was no spark.Wired coil directly to battery (with a ballast resistor in line)Car run fine for 10 days.Now car runs for a minute or 2 then stops.Will start right back up.Check the coil wire with a tester and there is a momentary power outage and the car stops.Changed coil,no differnce.Any ideas?Also anyone have a wiring diagram for car?(Not Chilton or Haynes)
