There's an option to limit run time on the app setup. If you've ever used the irobot home app with this device, I'd start by making sure it's not set to limit run time in the app. If not, probably consider replacing the battery pack, which is a pretty simple task on these.
Likely, the battery is having an issue. When it stops working, does the battery take the full time to charge? Otherwise it could be an overheating motor or something like that
