My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
If all of these codes set every time this issue occurs this can be due to an internal intermittent electrical fault in the engine computer itself.I have seen this computer act up/fail before internally and cause this issue here and had to replace it.
This will have to be tested further to pinpoint for sure that this is the cause and the engine computer connections and wiring need checked for any damage needing repaired.
Thanks Pete
