May be this is because of there is no machinekey specified. You can give it a try -
Application pools can regularly be recycled. When recycling occurs, the ASP.NET will recreate a MachineKey, if there isn’t one specified in web.config. Machine key is used to generate Authentication ticket, so the newly recreated machinekey makes the current Authentication ticket invalid which causes users to logout. The solution to that is to add a <machinekey> section in the web.config file.
<system.web>
<machineKey validationKey="19127329C4588866D1120D7146F4C6A7B53F29DBEF58F890" decryptionKey="789AA0B220798EF1780914BBE9CCB681C285F31680014162" validation="SHA1" />
</system.web>
There are many tools for generating machinekey. you may try - http://www.developerfusion.com/tools/generatemachinekey/

Try setting the time when you creating the Authorisation cookie:
Private Sub CreateAuthorisationCookie(ByVal Role As String)
' Create and tuck away the cookie
Dim authTicket As New FormsAuthenticationTicket(1, txtUsername.Text, _
DateTime.Now, _
DateTime.Now.AddMinutes(15), False, Role, FormsAuthentication.FormsCookiePath)
Dim encTicket As String = FormsAuthentication.Encrypt(authTicket)
Dim faCookie As New HttpCookie(FormsAuthentication.FormsCookieName, encTicket)
Response.Cookies.Add(faCookie)
End Sub
The Custom Identity Class Imports System.Data
Imports System.Configuration
Imports System.Web
Imports System.Web.Security
Imports System.Web.UI

Imports System.Web.UI.WebControls.WebParts
Imports System.Web.UI.HtmlControls
Public Class CCustomIdentity

Private _ticket As FormsAuthenticationTicket
Public Sub New(ticket As FormsAuthenticationTicket)
_ticket = ticket
End Sub
Public ReadOnly Property AuthenticationType() As String Implements System.Security.Principal.IIdentity.AuthenticationType

Return "Custom"

Return True

Dim userDataPieces As String() = _ticket.UserData.Split("|".ToCharArray())

End Get
End Property
Public ReadOnly Property Title() As String

Dim userDataPieces As String() = _ticket.UserData.Split("|".ToCharArray())
Return userDataPieces(1)
End Get
End Property
End Class
The Custom Principal Class

_identity = identity
End Sub
Public ReadOnly Property Identity() As System.Security.Principal.IIdentity Implements System.Security.Principal.IPrincipal.Identity
Get
Return _identity
End Get
End Property
Public Function IsInRole(role As String) As Boolean Implements System.Security.Principal.IPrincipal.IsInRole
Return False
End Function
End Class
My Global.asax methods
Sub Application_AuthenticateRequest(ByVal sender As Object, ByVal e As EventArgs)
' Fires upon attempting to authenticate the use
' Get the authentication cookie
Dim cookieName As String = FormsAuthentication.FormsCookieName
Dim authCookie As HttpCookie = Context.Request.Cookies(cookieName)
' If the cookie can't be found, don't issue the ticket
If authCookie Is Nothing Then
Return
End If
' Get the authentication ticket and rebuild the principal
' & identity
Dim authTicket As FormsAuthenticationTicket = FormsAuthentication.Decrypt(authCookie.Value)
Dim roles As String() = authTicket.UserData.Split(New [Char]() {"|"c})
Dim userIdentity As New GenericIdentity(authTicket.Name)
Dim userPrincipal As New GenericPrincipal(userIdentity, roles)
Context.User = userPrincipal
End Sub
Private Sub Global_asax_PostAuthenticateRequest(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PostAuthenticateRequest
' Get a reference to the current User
Dim usr As IPrincipal = HttpContext.Current.User
' If we are dealing with an authenticated forms authentication request
If usr.Identity.IsAuthenticated AndAlso usr.Identity.AuthenticationType = "Forms" Then
Dim fIdent As FormsIdentity = TryCast(usr.Identity, FormsIdentity)
' Create a CustomIdentity based on the FormsAuthenticationTicket
Dim ci As New CCustomIdentity(fIdent.Ticket)
' Create the CustomPrincipal
Dim p As New CCustomPrincipal(ci)
' Attach the CustomPrincipal to HttpContext.User and Thread.CurrentPrincipal
HttpContext.Current.User = p
Threading.Thread.CurrentPrincipal = p
End If
End Sub
And Finally my Main Web.config
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" cookieless="UseCookies" name=".ASPXFORMSAUTH" protection="All" slidingExpiration="true" timeout="15" defaultUrl="~/Login.aspx">
<!--SlidingExpiration=timeout reset with each request
Timeout in minutes
Protection=validation and encryption=ALL-->
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
So with that in place i am able to control the timeout. Hope it helps you.
