What are the potential causes for the Audi 80's ignition not working properly?

I have an Audi 80, and my ignition seems to be having issues. Sometimes it won't start at all, and other times it starts fine but then stalls out. I've checked the battery and it seems to be fine. What else could be causing this issue?

One potential cause for your ignition issues could be a faulty starter. This can lead to inconsistent starting and stalling, as the starter is responsible for initiating the ignition process.
