It doesn't make sense to me that code would generate intermittent hang ups. Our system worked fine before the failure, and then again after rebooting. That implies something outside the code is influencing the system.

As far as I know it is not possible for the field to cause a Watchdog error.
EDIT: It sounds like, based on the document that StephenB linked to that communication problems could potentially cause the system Watchdog to time out.
Depending on the structure of your code it may be possible that one specific case somewhere or one value for a sensor or variable causes a hang that times out the User Watchdog. The robot gets cycled through a specific set of modes on the competition field that may not be the same as what is happening when you are testing on the practice field.
