Engine stalling while driving. "Too many primary trig"

[AudimanS4]

Hello everyone, I am having an issue I can't quite figure out. I have a 95 URS6 with the AAN engine code which is running VEMS. And recently it has started to stall and stop while driving normally.

I get the error code "Too many primary trig" while looking at the live data on VEMS. Does anyone know what the issue is? The strange thing is that sometimes the engine runs fine but most of the time it stops multiple times after restarting it.

Best regards Audiman

How old is your ignition switch?

I've only owned it for 8 months or so, but I am guessing it's the original one..

Update: Talked to Marc at EFI express and I replaced the G40 cam sensor. Car has been running great ever since so that was the issue.
