Update in case anyone else runs into this same problem in the future: I tried porting my code to use Net::OpenSSH but due to the platform I am targeting, I just could not get it working properly. The entire connection would sever and then re-establish and prompt for password after each command. I also had the same issue with Net::SSH::Expect. The solution I came up with was to implement a counter and after 20 iterations, sever the connection cleanly and re-establish for another 20 lines indefinitely. Everything now seems to be in working order. Added code snippet below. Thanks Monks! 
if($i == 20){
            print $channel "logout\n";
            print "$_" while <$channel>;
            print "\n";
            
            $channel->send_eof();
            $channel->close();
            $ssh->disconnect();
            undef $ssh;
            $ssh = Net::SSH2->new();
            $ssh->connect($host, 22);
            $ssh->auth_password($tacacsusername, $tacacspassword);
            $channel = $ssh->channel();
            $channel->blocking(0);
            $channel->shell();
            $i = 0;
        }
