Hello everyone.Recinitly i bought a 64 and half mustang.It has the crane cams fire ball electronic ignition converstion set up in it.When i drive around for a while and get the car hot,the car just stalls and it won't fire back up again till it cools down.When this happens i checked and theres no spark.I installed a balast resistor between the ignition wire and the coil and it still does the same thing.Anyone know what i should do.
