Hi there,

The most common issue for this is a broken ground wire. This could be the negative battery cable, or any of the ground straps that go from the engine to the firewall. The bad ground will cause a voltage fluctuation and cause the coil to burn up, melt or finally just stop working.

Check any grounds you can find on the engine and grounds that run from the back of the engine to the firewall.
