You can let CloudWatch terminate your EC2 instance and let AutoScaling bring up another "fresh" instance with your application configured.

If only your application halt but EC2 instance works.

You could write a shell monitor the app using CloudWatch API and shoot the app when necessary,then make it a task in cron. Or you can using a shell right in your EC2 instance.

To restart your EC2 instance automatically is way too dangerous ,you can try Autoscaling, which automatically starts a new instance when your instance frozen and keep your SLA.
