GMC Sierra TPS sensor

My truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor. Can any help thanks!

By the way it's a 2010 gmc Sierra 5.3 4x4

If this is drive by wire there is a tps as part of the gas pedal as well as the one on the throttle body.
