Why is my data reader closing?

I have a method which retrieves a IDataReader and attempts to load object data using this reader. The problem is, before it gets to the next record using IDataReader.Read(), it is closing. Nothing in my methods closes it......any guesses?

Code:

---

        public void DataPortal_Fetch(ProjectInfoListCriteria criteria)
        {
            string query = "SELECT A.*, B.* FROM tbProjects A INNER JOIN tbAwardedProjects B ON A.ProjectID = B.fkProjectID ORDER BY B.ProjectNumber ASC";
            using (InformConnection c = InformConnection.Instance)
            {
                this.IsReadOnly = false;

                IDataReader rdr = c.ExecuteReader(query);
                while (rdr.Read())
                {
                    ProjectInfo info = ProjectInfo.Create();
                    info.ReadIn(rdr);

                    ProjectAwardedInfo awarded = ProjectAwardedInfo.Create();
                    awarded.ReadIn(rdr);

                    info.AwardInfo = awarded;
                    this.Add(info);
                }
                this.IsReadOnly = true;
            }
        }
 
/// The ProjectInfo.ReadIn(...)
      public void ReadIn(IDataReader rdr)
        {
            LoadProperty(IdProperty, rdr.GetInt32(rdr.GetOrdinal(IdProperty.Name)));
            LoadProperty(NameProperty, rdr.GetString(rdr.GetOrdinal(NameProperty.Name)));
            LoadProperty(CityIdProperty, rdr.GetInt32(rdr.GetOrdinal(CityIdProperty.Name)));
            LoadProperty(CreatedProperty, rdr.GetDateTime(rdr.GetOrdinal(CreatedProperty.Name)));
            LoadProperty(AddressProperty, rdr.GetValue(rdr.GetOrdinal(AddressProperty.Name)));
            LoadProperty(DirectionsProperty, rdr.GetValue(rdr.GetOrdinal(DirectionsProperty.Name)));
            LoadProperty(SitePhoneProperty, rdr.GetValue(rdr.GetOrdinal(SitePhoneProperty.Name)));
            LoadProperty(SiteContactProperty, rdr.GetValue(rdr.GetOrdinal(SiteContactProperty.Name)));
        }

The ProjectAwardedInfo.ReadIn(...)

        public void ReadIn(IDataReader rdr)
        {
            LoadProperty(IdProperty, rdr.GetInt32(rdr.GetOrdinal(IdProperty.Name)));
            LoadProperty(NumberProperty, rdr.GetString(rdr.GetOrdinal(NumberProperty.Name)));
            LoadProperty(EstimateIdProperty, rdr.GetInt32(rdr.GetOrdinal(EstimateIdProperty.Name)));
            LoadProperty(AwardDateProperty, rdr.GetDateTime(rdr.GetOrdinal(AwardDateProperty.Name)));
            LoadProperty(ClosedProperty, rdr.GetBoolean(rdr.GetOrdinal(ClosedProperty.Name)));
        }

As you can see, there is nothing closing my DataReader object. Therefore, why is it being closed?

Maybe the connection is being closed? Take a look at InformConnection.Instance (is any other class closing that instance while it's being used?).
