Good Morning,
So the coil wire was replaced. Sunday, went for a 15 mile run to visit a friend. Car ran great. After an hour visit, car wouldn't start.
Replaced coil wire (again) and drove 10 miles and car died at red light. Had an extra coil wire, installed and drove 5 miles home.
Got in garage, waited 10 minutes, it would not start.
Monday, called Mfg of new coil "MASTERPRO IGNITIONS", nice people, recommended a ballast resistor or a coil with an internal resistor. On line they are used on Ford tractors.
I have a ballast resistor, should it be installed ?
Any other problem solving ideas out there ?
Thanks in advance,

My coil wire was the same, burnt at the end going into the coil.
Thanks for you help.

My buddy's 64 Galaxie had the same problem.  It would run fine then out of nowhere it wouldn't start.  I chased it for a week and it finally quit long enough for me to find the problem.  His ignition wires had carbon centers. One end of the coil wire was burnt causing the spark to jump the gap.  It's been about a year with no more problems.   Lesson learned. 

Earlier I remarked about the '56 Fairlane with electronic distributor and modern Summit carb and how it got
hot and would't start.
Well, I was advised to replace coil wire. Did so, went for 10 mile run, no problems, returned home, let car idle
in place for 10 minutes, no fan, turned off, restated in 10 minutes. NO PROBLEMS...FIRED UP LIKE IT ALWAYS!!!
Happy Farilane owner.
Thanks to all for the advice,
