Note that there are two Team Issue variants. If you open the .PDF files, they've got the exploded views and assembly instructions. One uses a wave washer between the left crankarm and the bottom bracket, the other doesn't. They're not adjustable in the usual sense.
Whichever variant you have, the place to start is to make sure all the parts shown are actually present, including the slim little blue O-rings that go on the crank spindle. Also, ensure that the bottom bracket's bearing cups aren't loose in the frame, which can be done with the Park Tool BBT-19 and a ratchet or breaker bar.
If you find that it was just a loose bearing cup, then tighten it properly, reinstall the crank (making sure to get all the parts in their proper places), and see how it goes now. Note that you are supposed to use a specific type of LockTite (see the .PDF files). If there were parts missing, they can be ordered via your local bike shop, who can get them from Quality Bicycle Products.
If you want to bag it and get something else, Shimano has their act together a little better IMHO. If your bike is a 3x10 then the Shimano 105 would be a contender.
Oh, and bigger picture: if your chain falls off the middle ring under high torque, also inspect the middle chainring very closely for bent, gouged or nicked teeth.
