Connection String - SQL Conncetion through C#

I am receiving a SQLException in my code - a Timeout Expired exception.  My code calls the connection string from a config file where the "connect time" is set to 180.  The query takes about 41 seconds in SQL but I am getting the exception at 30 seconds.

------ C# code in the DBHelper Class ----------------------------
        internal static DataTable dataCommand(string command)
        {
            SqlConnection sqlConn = ConnectToDatabase();
            IDbTransaction transaction = sqlConn.BeginTransaction();
            DataTable dt = new DataTable();
            try
            {
                Database db = DatabaseFactory.CreateDatabase("MyDB");
                SqlCommand com = new SqlCommand();
                com.CommandText = command;
                dt = db.ExecuteDataSet(com).Tables[0];
                transaction.Commit();
            }
            catch
            {
                transaction.Rollback();
                throw;
            }
            finally
            {
                if (sqlConn.State == ConnectionState.Open) sqlConn.Close();
            }
            return dt;
        }

        internal static SqlConnection ConnectToDatabase()
        {
            SqlConnection sqlConn = new SqlConnection();
            sqlConn.ConnectionString = ConfigurationManager.ConnectionStrings["MyDB"].ToString();
            sqlConn.Open();
            return sqlConn;
        }
------------------------- End of Code -----------------------------------
------------------------App Config connection string -----------------

        connectionString="Data Source=indypro2\test3200;Initial Catalog=MyDB;
    User ID = MyUserName;Password = MyPassword;connect timeout=180;"
    providerName="System.Data.SqlClient" />

------------- End of connection string -------------------------------------

When I break at the SQLConnection I can see the timeout is set to 180 but it continually fails.

Suggestions?
