Dodge dies when making left turns

my 2005 Dodge Ram (53,000 miles) will sometimes die while I’m making a left turn, or when I’m moving slowly in a parking lot.I get the oil change regularly and asked my mechanic to checkinto it. He. thought it has something to do with using cheaper gas, so I started buying the more expensive gas but it is still doing it. This is scary when it happens because not only do I suddenly slow down, but the power steering goes out and I have to muscle it around the turn. Any suggestions?

Have your mechanic thoroughly test your fuel pressure system. Also have him hook up his scanner and retrieved any possible fault codes and look for any unusual data.
