Hi @CedricOsei
Many a time the flow becomes turn off due to inactivity after 90 days. To handle those cases, we can set up monitor flow that can turn suspended flows back on using power automate for admin connector.
Here is a sample flow:
We will set up a schedule flow for monitoring purpose and using "Get flow" action get the metadata of the flow:

Next, check the state of the flow and if found suspended then turn it on using "Turn on flow" action

This way we can turn on the suspended flow automatically with no or minimal down time.
If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.
Thanks
