It seems to happen about once a month (has happened twice now). Any idea what causes this? I am due for a 45,000 mile service, so I would like to mention it to the mechanic.

first, its not the starter. if you turn the engine over, its working. the starter might be weak or etc from all the cranking though. but its not an issue
as for hitting the gas there is SO MUCH to check out. it can be a fuel pressure regulator. if its stuck open (too much) then when the vehicle runs the exhaust will smell quite gassy.. if its not getting enough pressure obviously it stumbles when you get on it. also your injectors might be stuck or clogged, could be a computer failure or a mass air flow sensor failure. could be a type of sensor like a coolant temp sensor that tells the cpu that the car is cold therefore needs more gas to warm up. could be an iac (idle air control valve.. i dont even know if theres something like that on your car, if so it may be something else).
i wouldnt recommend ripping into that stuff since its pretty technical and theres many many parts that rely on everything else. i say drive it and see if it gets real bad, if it only happens once a month or so i wouldnt worry about it - CHECK YOUR FUEL FILTER IT MAY NEED CHANGED(few $). if it gets worse take it to a scion dealer!
