I will try to answer because your listing is showing as a Ford product and you may not get another mechanic for your brand with a wrong category.

You need to measure the voltage in the system. You can get a free charging system check at most big autoparts places like Autozone,etc.

Now too much voltage will kill a coil. You also need to see if the original wiring has been changed or patched. The makers often put in resistor wiring in the coil circuit to reduce voltage. Any changes will allow different voltages to reach the coil.

Heat is also a factor. An experienced Mopar mechanic will have seen common problems and heat failure can be one of them.

You need to find out the operating voltage limits or Manufacturers specs.

The charging system check will show if the Voltage regulator in your Alternator is set too high.

Please rate my info.
