Default Throttle body relearn issues

I have a new 90mm throttle body (DBW) on an LS2 with a GTO pedal (also DBW). I did a throttle body relearn a few times. Engine on 3 minutes, off for 1 minute, 3 minutes at idle again. 1 minute off. The engine now sees the pedal and it revs just fine. Let it idle for 20 minute or more and it idles steady at 1K rpm. I drove it on the street over 45 mph varied the speed and shifting, but it will die after a few minutes. Did this a few times today. Runs fine for a while then the throttle dies. I'm looking at bi-directional scanners to do a computer based relearn. Any help with either throttle body relearn procedures or scanner advice is greatly appreciated. Also, new MAF sensor and MAP sensor.

Thanks

yes, you will need a good scanner/computer. This one is excellent for the money:
