My car is stalling

I just had my power steering pump and hose replaced. I drove my car then the next morning it started I went to drive and it cut off. I replaced the battery and also had and oil change and replaced oil filter. It started I drove around the block and it cut off again and would not start. I did notice that it seem to be pulling as I accelerate. Please help not sure what could be the problem. Also I had a new distributor cap put on the vehicle as well.
