What's your voltage at the coil while running? I'm wondering if your ignition resistor is going bad and dropping too much voltage, leading to weak spark under electrical load.
Checking at the ballast, to the coil 5.4v with no load. Was going to check with a load but realized i can't because my headlights arn't installed. It's at 4.68v fully loaded minus headlights lol....
after temporarily putting headlights back on it dives into the low 4's high 3's as it dies.
