lose one's nerve

Get cold feet

To lose one's nerve is to suddenly lose courage or confidence, especially at a critical moment when action is required.

Someone who loses their nerve backs down from something they intended to do: He was going to ask her out, but he lost his nerve at the last second.

The phrase implies the failure was psychological rather than practical—the person could have acted but fear stopped them.
