Trouble starting then shutting off?

My car has been having issues starting for a few months. Yesterday I tried about 30 times to crank it, and it finally started. Then, about 2 miles down the road, it slowly stopped accelerating, and the steering wheel locked up, and it shut off. It wouldn't restart, and sometimes the key would get stuck while attempting to crank, and it would keep on and make a clicking sound constantly. I got someone to jump my battery, and I barely made it home with the same problems (which was maybe 2 miles). Also, if I slam the accelerator, I could go a little bit, but if I push it normally, I wouldn't go anywhere.
