The same thing happened to my truck. It Lost power and entered in safe mode every time the check engine light turned on.  It turned  out to be broken ground wire. All I did to fix the problem  was replace the broken wire, deleted the error code, and it didn't return. My advice to  you is, that before you spend any money buying new expensive parts, check all the wiring connected to your throttle.
