Engine Safety Tab

I have O2 lean out protection enabled to envoke a rev limit of 3500rpm. The other day tuning, I triggered the 02 lean out protection and the rev limit kicked in like it should. I adjusted the fuel and proceeded to do another pull. During the pull the car was not able to accelerate above 3500rpm. It was like my rev limit was set at 3500 ( I was not triggering lean out protection). I put the car in neutral and reved the engine and it would not rev above 3500 in neutral sitting still. I had to shut the car off to reset the ecu to get rid of the rev limit. Then after doing another pull I hit the lean out protection again and the same thing happened. Its like the lean out protection does not reset after it has been triggered unless I shut the car off.
