Logic Pro And Motu Traveler Issue

This is a wierd one. I've been using this setup on a live TV show running click to band rhythm section and additional sequencing to two other stereo pairs out of the Traveller. It can be fine all day - 5/6 hours - then when it comes to the broadcast, I can check the track several times - all is fine - then at some point, it will just not send audio from the outputs of Logic, and the Traveler shows and outputs nothing. Re-launching Core Audio does not resolve the issue, nor does re-booting the Traveler, factory resetting the Traveler, or re-launching Logic Pro. I have re-created the issue at home by leaving the configuration on overnight. In the morning the issue occurs - it appears to be a time thing, not dependant on whether the program is being used or not i.e. it can happen during use as well as after a long period of inactivity. I have not tried previous versions of logic to work around this yet, but I used to use 7.0.1 with MOTU Firewire driver 1.2.5 (2005-05-10) before and don't recall the same issue. This issue occurs in Logic 7.1.1 with MOTU drivers 1.2.5 (2005-05-10) and 1.4.1 (2006-02-28). I have nothing else running, e.g. Widgets, Screen Savers, No Energy Saver settings, all non-essential software is disabled/closed. It occurs with or without firewire bus power or a separate power supply. If I swap back to Built-in audio as my Audio driver I can play stuff through the internal speakers, but if I then switch back to MOTU Traveler as the Audio device the problem is still there. The only way out is to re-boot the machine - which is re-loading the driver, I guess.

Any help would be gratefully received
