I don't quite understand everyone's problem. I've thrown cars around in an empty lot before to test the limits of my cars in the past.

The OP's questions were answered. He's in limp mode.
To the OP: You didn't let out of gear during the spin nor did you gas the throttle to compensate for the spin which probably put you in limp mode. Most do the battery disconnect. Just make sure you have your radio code on you if you need it.
