You may first verify that if you run  the test  separately, it works fine.

Here is an article about debugging web test in load  test you can refer to: http://blogs.msdn.com/b/slumley/archive/2007/11/19/debugging-errors-in-load-test.aspx

In addition, there is a new feature named 'saving test logs' you can take a look for better troubleshooting:(With VSTS 2010, Load Test users now have the option of capturing and saving the entire result of individual tests run within the load test such as a failed Web test or a failed unit test.   This feature makes it easier to debug problems that occur when running tests within a load test that do not occur when running the same tests outside the context  of a load test.)
