Describe the current behavior
Colab Pro+ runtimes are terminating much earlier than expected, typically within 40 minutes to about 1 hour, even while the notebook is actively running. When the session stops, the runtime is fully reset and all in-memory progress is lost.
In addition, background execution is not working. If I close the browser tab, the session does not continue running and instead stops shortly after.
This has led to multiple interrupted runs and loss of compute units on jobs that never completed.
Describe the expected behavior
Runtimes should remain active for extended periods (up to the Pro+ limits) when executing long-running tasks. Sessions should not terminate while actively running.
Background execution should allow notebooks to continue running after the browser is closed, as expected with a Pro+ subscription.

Google Chrome
Additional context
This issue has been consistent over the past few days and affects long-running training jobs. No changes were made to the notebook setup or execution pattern.
