Hello Will,

In the video looks like the green light cut out momentarily when you partly release the throttle (during the sound of engine goes down a bit). Or was it the throttle was steadily maintained but the engine cut out nevertheless?

There is fuel cut-out during throttle release (part release or full release) to reduce emissions. Fuel pulses depends on feedback from the CPS but totally controlled by the ECU (as in case of throttle release). On Bosch LH system all fuel injectors are fired simultaneously (common mode injection) only the sparks are timed to specific cylinder.

Does your engine uses distributor sensor for spark? Usually for 1990 model and above it doesn't (the CPS is used instead). But just in case it does, check its electrical connections (for that sudden loss of spark you've mentioned).

Distributor with hall sensor for spark.

Regards,
Amarin.
