Default LT1 studdering after sharp turns!

So I made a sharp turn to day and went to go accelerate and It didn't go anywhere, I look at my TACH and it's at zero. I hit the gas about 3 seconds later and it pops back up and drives fine. Did it again coming home and it did the same thing, went down to zero while still running and then slowly came back up. NOW I went down my street did a quick jerk of the wheel and did it. This time it kept stumbling and stumbling. Sounded like it was running on one cylinder. I drove it three blocks back to the front of my house. When I gave it gas it woudn't do anything except try to die. So I idled it home basically just drawing out a little bit.

I let it cool, came back out, it started up and ran fine.

NOw in the process of writing this I had a neighbor scan it for me. This is what I got.

P1361
P0430- Catalyst Below Threshold (bank 2)

HELP!

I'm thinking O2 sensor but that doesn't explain why it craps out only on sharp turns!

gas was 3/4 full.

Now whenever i start it, it won't even run good so I'm going to unplug the o2's and see what it does. If thats it time to get 2 new ones. What are the best kind to get?
