Power Steering Pump problems of the 2006 Chrysler 300C

I have had this car for 7 years, never had an issue. On February 23,2014 I went to shell and filled up the car with $49. 00. I do not remember if I ever filled the car up before. I'm sure I have but I usually put 20/30 bucks in. But I just found out about stop n shop gas savings and received a discount. I tried to put 50 in but it only took 49. 00. I got back in the car and I tried to pull away from the pump and it shut down. I thought maybe it was a fluke since I was basically at a roll. I drove 2 blocks and at the traffic light it died. I proceeded to make a u-turn to return home. The car died 3 times in a 5 block span. I took the car to my cousin who had a computer, no codes came up but the car shut down twice. I parked the car and took out a different car. My cousin thought it was bad gas or a bad oil change which I had done on Feb 22, 2014 I just returned home and googled, "Chrysler 300c stalling" and found the article that this has been occurring, and here I am. I guess I will contact Chrysler in the morning.

I had just refueled (filled up - did not continue fueling after the pump auto-stopped) and continued driving to my destination (about 3-5 minutes). I had just completed a left turn, approaching a red light, so I was "coasting" at about 15 mph when the engine died. Luckily, I was beside of a vacant parking lot and was able to veer into the lot and off the highway. However, in doing so, I noticed that I had lost steering capabilities and it was very difficult to steer the car off the highway. It was a good thing I wasn't driving at a higher speed and going around a curve, because I would've surely wrecked. The instrument panel was still lit up (compass, odometer, radio station, etc), but the engine light came on. After stopping, I placed it in park, turned off the switch and restarted the car. There was some hesitation, but it did start. Continuing to my destination, I could occasionally feel the car "sputtering" or hesitating like it wanted to shut down again, but it did not happen again before I made it home. However, on my way to work this morning and before I left my driveway, the car acted like it wanted to die again. I had backed out of my garage and put it in drive, slightly pressed the accelerator and it "sputtered". It continued "sputtering" periodically on my way to work (6-8 minute drive). I am really becoming very nervous about driving our country roads, in fear that it will shut down and I will lose the ability to maneuver the car to safety until I can regain power.
