My reduced engine power message is on my dash screen, and check engine light

What is your question?

When it first happened, I could only accelerate up to a/b 20 mph. I had it scanned and it read codes P1125,P2138. I replaced accelerator pedal and throttle position sensor. Cleared the codes and it drove fine for a day and it happened again. I checked the wires and fuses and could not find anything wrong. Autozone put their scanner and it pulled the P1125, P2138 codes once again..but also the codes C0035,C0040. These are wheel sensor codes,but my truck is stopping and braking just fine, no ABS lights or anything.. before I spend anymore money on a throttle body, could these codes correlate to my reduced engine power message? if so how? thanks
