Help needed with Cuckoo clock

I have a Cuckoo that is about 17 years old I got in Germany, has been sitting idle for at least 8 years. I started using it recently and it works well and keeps time, but after some time (usually within 1 day) it just stops. It seems like it always stops with the weight in the same position, that is halfway between the top and bottom of it's travel. Any help is appreciated

Look at the chain links. One may be bent.

Next check for bent teeth on the great wheel or 2nd wheel.

If the clock is failing 12-15 hours into the 30 hour cycle, it is unlikely the problem is some sort of interference unless that is in the going works. Everything else repeats itself every hour or almost every hour. If there were interference, the clock would probably not want to start after the interruption.
My guess is that your clock has a power problem and the failure has little to do with the 12-15 hour cycle. I do not think clean, oil and adjust will solve your problem and I do not believe a novice will be able to make it run and be dependable.
Cuckoo clock movements are known to wear and cause service problems. That wear will result in poor performance.
It might be time to take the clock to a qualified technician and have him/her evaluate the situation.
Best,
Dick

Dick makes a good point. When the clock stops, do you have to rewind it to get it started again, or will it start and continue to run?
