Fail safe mode help
 

I am really desperate. I have a 2010 ford explorer sport trac that keeps going into a fail safe mode. I have gotten a code p2104. I have replaced the tps with a BWD sensor. I continue to go into a FSM. I then replaced the motor ( Dorman ). I also went into FSM. I went to ford and check to see if they can check the codes. They said they could not find anything and said it may be a pedal position sensor. Finally thinking that they were able to reset the computer I was able to drive 226 miles before FSM again. Had the code read again and I got a code for EGR. So I replaced the EGR with a motorcraft part. What do you know I went into FSM again. What do I do next. I can replace the tps with a motorcraft part? I can replace the whole throttle body? The only ones I am finding is a1 cordon 67-6000 and spectra tb1014? Any advice would be greatly appreciated
