Hello and welcome! My name siCustomerand I can assist you with your question. What is the fuel pressure at when this happens? Just because the fuel pump has been replaced does not mean the fuel pressure is within specs. You might want to double check it to be sure.

Expert:  Amedee replied 4 months ago.

Another possible cause would be a bad engine coolant temp sensor, throttle position sensor and or a bad MAP/MAF sensor. They call can affect the fuel delivery and can cause a hard/no start condition if they were to go bad.
