Mr. Silver, is there a chance you have a bad batch of tubes? Our LBS had cyclists coming in by droves with flats. I believe the bad batch of tubes were Specialized. They switched to Bontrager and it reduced the incidents of flats.

I had something weird happen not long ago. I purchased new Specialized Captain tubeless tires and it would go completely flat over night. The bike mechanic took soapy water to it and air bubbles developed all along the sidewalls. Needless to say I switched tires.
