Sounds like a bad coil to me. You can switch the coils and see if the problem moves to confirm this

if there wasn't any problems before the water and head gaskets i'd be looking closely at connections

Half of the function of the coil is to get the necessary voltage to create the magnetic filed.
The second half of the function of the coil is for that field to be interrupted. It is the collapsing of the magnetic field across the secondary which allows the jumping of the plug gap.

Checking the plastic plugs and making sure the individual plugs are actually connected.

The ignition module is part of the triggering as is pulse generators.

Sometimes going over it again can solve the problem.

Myself, I take notes, so if it happens again, I have a reference. I have volumes of notes......

I hope this helps.
