Car will not stay running when reservation mode is set

Question

2011 mustang gt, option for manual transmission is selected. When performing reservation mode the relay clicks 3 times and flashes blue then red. When key is turned off the car shuts down and does not remain running. Seems to be the bypass is not working I tried both options. Two key programming and the decryptor option. Does anyone have any ideas why this would be? Using thar-for4 harness. Harness A door immobilizer is being used not b as the manual suggests
