If you want to use sudo su - user without a password, you should (if you have the privileges) do the following on you sudoers file:

<youuser>  ALL = NOPASSWD: /bin/su - <otheruser>
where:

<yourusername> is you username :D (saumun89, i.e.)
<otheruser> is the user you want to change to
Then put into the script:

sudo /bin/su - <otheruser>
Doing just this, won't get subsequent commands get run by <otheruser>, it will spawn a new shell. If you want to run another command from within the script as this other user, you should use something like:

 sudo -u <otheruser> <command>
And in sudoers file:

<yourusername>  ALL = (<otheruser>) NOPASSWD: <command>
Obviously, a more generic line like:

<yourusername> ALL = (ALL) NOPASSWD: ALL
Will get things done, but would grant the permission to do anything as anyone.
