When the problem is ongoing, check for primary voltage at the coil, pink wire, Shouldn't have any voltage with the key off. If it has voltage with the key off, you need to check the circuit, connectors and wiring. The circuit could be shorted to voltage?
If no primary voltage at the ignition coil, then no spark and the vehicle is dieseling for some reason, Too high compression, cylinder temp too high maybe a hot spot?
