Dodge 1500 2005 powering off randomly. Any ideas?

Dodge 1500. Year 2005. V8. Powering off
about 3 times. Has a little over 80k miles.
So far I have noticed one thing that I do with
my truck everytime it powers off. I make a
turn. First time I made a wide turn was
going very slow and the steering wheel
locked up and the truck slowed down and if
I pressed on the gas it didn't go anywhere. It
just slowed down to a creep and shut off.
All the lights were still on. No check engine
lights. Turned the truck off and it came back
on. The second time I had made a sharp
turn and it powered off again..same exact
thing as last time. Steering wheel locked up
and lights stayed on but truck was off. 3rd
time I backed up and started driving I guess
I did turn a little bit and it powered off. This
time I didn't notice if the steering wheel
locked up or not. It has gas and oil. No
codes are showing up when I take it to the
dealership. I was driving slow each time it
had powered off. I want to know what is
wrong with it.
