Unless you know what you're doing, you should not do this, especially in a multi-user environment, otherwise, you're just exposing yourself to brute-forcing.
If you know what you're doing, the sudoers option you're looking for is passwd_tries. From man 5 sudoers:
passwd_tries
The number of tries a user gets to enter his/her password before sudo logs the failure and exits. The default is 3.
So, you can set this to a higher value to meet your need e.g. in /etc/sudoers you can put:
Defaults passwd_tries=100
to have 100 attempts prompts.
As a side note, always use sudo visudo to open /etc/sudoers (to ensure sanity checks), don't open it in manually in editor.
