This is most likely a fuel issue. However, I suspect the fuel pressure that you have is not correct. Did you use a pressure gauge as shown in this guide?

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

The reason I ask is because that is high for this vehicle. The spec is attached below and with the regulator connected it should not be higher then 30 PSI.

If this pressure is correct then I suspect the regulator is the issue. It is located on the fuel rail so I would check the pressure with it hooked up and disconnected.

I attached the info on this below. Let us know what you find. Thanks
