Power Steering Pump problems of the 2010 Jeep Compass

After purchasing my new/used Compass from a dealer in town I went to fill the gas tank up. Not really a problem this time filling the tank but upon stating the vehicle it started to stall shake , spit, and sputter down the road after only about a 1/10 of a mile. During this time of stall the steering became almost impossible to turn while driving towards oncoming traffic . This wasnt the only time it done this . . . . No every time I go to fill up the tank with gas it does the same thing and acts the same way it straightens up after running a few miles (if it stays running ) or restarting the engine. Lately it takes me about a half an hour to fill the tank because the pump shuts off like it is about to over-spill except the tank is empty and it isn't the pump because it does this at every gas station I come to now. The safety factor here is the stalling while in motion without warning loosing control of where my car is going is a safety hazard and this needs to be address before a head on collision.
