Normally I would say that relay 109 is going off. Look under the dash board. look for the relay panel. What color is the relay?

If the relay marked 109 (or 601 if you're looking at it upside down) is black, replace it with the newer part which is grey. It can overheat and cuts power to the ecu which cuts power to the engine. It's possible that would also cause the immobilizer code.

From testing the immobilizer, I found that it shuts off the engine only a second after start. It won't shut the engine off while driving, unless yours is different.
