Why does my 2011 Hyundai Accent die as I turn the corner?

What is your question?

I have had a tune up last year, all my belts (alternator, timing, power steering and ac belts) are changed (at 80K miles), four new tires, alignment, new battery... what could it be? It's a pretty good car, but it dies when I turn the corner. It starts up right away, but the dial for the RPM stops working, until I start it up next time.
