Probable cause -
1) Poor connection going to the Tac module.
2) Failed Tac module
3) Check TPP or TPS sensor
4) Binding or bent throttle plate, or failed throttle body.
On a Drive-wire-system, if the signal is lost from the gas pedal to the TAC module, or throttle body , it will go into reduced power mode.
