Check your oil level. I had a similar experience where, from a cold start, drive 1/4 mile, take a 15 or 20mph turn to the left, and my TH would die. I'd coast to the edge of the road, and simply restart it.
I called my dealer with those symptoms and they said to check my oil. When I checked my oil, it wasn't even registering on the dipstick. I took it to my dealer the next day and found I only had 1 quart instead of 5. Now I'm doing an oil consumption test for them to find out what happened to my 4 quarts of oil they put in 3,000 miles ago.
But I was told that the shut down is a build in safety feature for when the engine can't suck any oil. When I turned, the little oil I had, sloshed to the right side, exposing the intake, allowing it to suck in air, then the car would shut down.
So check your oil and see if you're low.
