Thanks for the response but I don't think that's it unfortunately.
I just experienced the problem again and my application log in the event viewer has a load of errors for IIS that all say:
aspnet_wp.exe could not be started. The error code for the failure is 80070545. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed
and that the ACLs on the installation directory allow access to the configured account.
