Random site 500 errors, up and down. TargetInvocationException

Vote:

We are currentlly experience a odd, and new, issue on a production site. Essentially, the site will start throwing random 500 errors. It happens once maybe two times a day. Below is the details logged to the event log. It seems to go down with no explanation why. And, if it sits long enough, it will come back to life.

Below is the trace. Let me know if you have any ideas. Thanks in advance. - Brian
