65 Barracuda daily driver

Got a new starter relay and yet another ballast resistor. Cleaned more connections, checked and cleaned the distributor cap and rotor. Got a new 14GA fusible link to match the 65 amp alternator (was 16 GA before). It's still stalling when hot and then not starting. This sucks. I took a multimeter and tested a few spots. I get 12+ volts at the starter relay, about 10 volts at one side of the ballast and eightish on the other. Less than 6 volts at the coil with the ignition on. I'm still waiting for the new ECU plug. Probably won't be here until the end of the week.
