Answer 1

You should check your CloudTrail logs (the first trail is free) to see if there was any change to your schedule or lambda. It's abnormal for cloudwatch events scheduler to stop without reason. Sometimes, it can be as simple as missing permissions.

If you are unable to figure it out; you should file a support ticket with AWS to help debug this further.

There are also some instructions for specific issues in https://docs.aws.amazon.com/eventbridge/latest/userguide/eventbridge-troubleshooting.html
