Did not get a spark.

For grins, disconnected purple/green and grounded white wire
No spark

If it fails that test its the box per troubleshooting matrix. I had the same issue and replaced the 6al with a MSD 5520 street fighter box. The next "Might Shut Down" box that dies I'll change the Dizzy to a Flamethrower and be done with it.

Once I opened up the old box I found a slew of tin whiskers shorting it out internally. https://nepp.nasa.gov/whisker/
