Number one coil will melt down in five minutes of run time.
I would say that there is some sort of malfunction with either the control side of your coil that is causing the coil to stay energized or there is a problem with your spark plug. If the spark plug has no gap the electric current doesn't have anywhere to go but straight back into the coil. I would ask for help from one of the mechanics at YourMechanic to diagnose what is causing your coil to melt down and replace the spark plugs if needed.
