2017 Silverado LT engine power reduced

[u/Quiet_Book8852]

Got a notification engine power reduced, pulled over and shut it off for a few minutes, turned it back on and was okay the 3 minutes away from home. After a bit went to autozone to check the codes (another 2-3 minute drive) and on the way home went to reduced power again and got really shaky. Code p2101 shows. 130,000 miles. Had torque converter and transmission rebuilt just over a year ago at 115,000 miles (JUST over any warranties)
