My 2003 Tahoe stalls while driving and the it hesitates to turn off. After it turns off it will not turn on right away. It will start after maybe six to ten times trying, Then it start fine like their is no problem. then it will turn off again and again during the day. Sometimes it can go a week without turning off, but then it starts all over again. No codes are showing up. Please help

It sounds like you are stuck in 4 wheel drive to me or have a problem with your drivetrain switching. Make sure you are out of 4wheel drive 1st

I had to replace my Idle Air Control Valve and Throttle Position Sensor.

Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle.
1 run liquid fuel line/injector cleaner in 1 tank
2 check fuel lines for debris
3 change fuel filters
4 have fuel tank flushed
here is trouble shooting order less expense to greater.
