Start Up Click

07 Mazda 3 Hatch Grand Touring
I have 2K on my 07 Mazda3 hatch, 5 speed auto. After starting and driving away, I hear a click (almost a cough) in the engine compartment area at 11 - 12 mph. It only clicks once - does not click on subsequent restarts unless the engine is turned off.
The Mazda tech drove the car and heard the click but was unable to locate the source. He will investigate further when I can take the car in and leave it. I suspect it might be a relay...possibly one that locks the doors. I can't find a TSB that describes the problem. Any help would be appreciated.
