It is not illogical, for a processor to get some minor corruption as long as a low level voltage is still available (Capacitors, batteries). Especially if a component is "leaking", or not in spec.
GHD, Need a better description of your issue? If engine running around layout, it will sometimes give the not on track message, or are you talking about shutdown and restart during an operating session?
It is always good to do the battery test letting the engine shut down with power off. Listen closely. Even if it play for a few seconds but abruptly stops early, the memory may not be updated with changes. So some times battery really isn't good.
Other check is to do a Track Signal test with engine. Just because you always have 10 with other engines, does not mean the engine acting up is a 10. DCS Signal is not just TIU and Track. The engine matters too. Can be a bad signal transformer or inductor on the PS-2/3 board, dirty wheels and pickups(corrosion).
Lastly, just wait as mentioned. Give it sometime try 5 minutes and test. Bracket an interval if waiting corrects the issue. PS-3 needs time as the processor still runs off the supercap even after sounds and lights are off. Should only be a few minutes, but it matters. This was also seen with Factory resets on PS-2/3, when being used with DCS Remote CDR. If you moved from the factory reset to the DCS Remote too fast the factory reset was not completed and the DCS Remote would not work. This is not common, but it is not rare either. G
