When I shut my rover down, I kill the power to the Sabertooth first, because I am not using the Sabertooth BEC to power my APM1.4, then turn off the APM, which is powered by a separate battery/BEC, and then my R/C transmitter.
If you are using the Sabertooth BEC to power the APM, then turning off the Sabertooth will shut both of them down. With no power to the Sabetooth, the motors should not keep on running. Do you have a switch in the battery line connected to the Sabertooth so you can remove battery power from the Sabertooth?
I have noticed that if I shut my transmitter off with the APM and receiver still on, the receiver output stays at the last received joystick/switch positions which are the center values for the joystick and the manual mode for the 3-way switch. The receiver also shows a loss of signal. I am using Spektrum equipment.
I do not understand why the APM is not sending the neutral position signal (1500) to the Sabertooth upon loss of the transmitter signal. Do you have a receiver tester so that you can look at the ouput of the APM steering and throttle signals when you shut down the transmitter?
I am using an APM1.4/Oilpan so I cannot duplicate your configuration. What brand of R/C equipment are you using? Also, what version of the ArduRover2 code are you using? The last version that JLN produced was version 2.20b. I am presently using the latest version of the ArduRover v2.30 alpha code from the GitHub.
