Have you had the vehicle checked for any engine codes, is the check engine light on. Before you have another fuel pump replace, have some one actually check the fuel pressure. It seems you may have a possible crank sensor issue but I can't tell for sure because I am unable to verify the concern. Have the vehicle checked for code. It seems like you've waisted a lot of time and money replacing thing that that are way out of the norm. Its hard to diagnose intermittent issues. I could be a bad wire that seperates when it gets hot. This issue may take time and someone very skillful with electrical and electronics see if you have any code I'm the memory program or pending program. Than have the actual fuel pressure checked while it won't start if fuel pressure is good fuel pump is good. Then have them check for injector pulse, if there is no pulse you may have a bad crank sensor. I have seen then cause this type of issue. But testing has to be done while symptom accures.
