Two thoughts

Does the GEMS system have the same idle stepper motor as the 14CUX? That was the cause of mine cutting out and a decent replacement cured it

As for the ignition amplifier, I changed that with no impact. Not sure if I still have the old one but you are welcome to it if I have. I’ll check later if you like?
