I've seen this a couple of times where an autorec works fine for a few weeks / months and suddenly stops recording programmes.
No further entries show in the upcoming recordings tab, and nothing goes into Failed or Removed Recordings.
Disabling and enabling the autorec has no effect. The only way to resume recording is to delete and recreate the autorec.

I have an autorec that is currently exhibiting this behaviour, even though there are matching programmes in the EPG, so happy to try some debugging
