2000 ranger 3.0 loosing fuel pressure when hot under load

So my 2000 ranger 3.0 flex fuel will start and run fine for about 15 minutes, then starts loosing fuel pressure only when under a load. You can push the clutch in and give it gas and the fuel pressure won't move. I put a fuel pressure gauge on it while diving and its stays between 50-60psi until it starts acting up, then will slowly drop down to 20psi and starts to backfire. At that point if you shutdown and restart fuel pressure will go back to 50-60, until about 15 minutes of driving and it starts dropping again. I've replaced crank sensor and camshaft position sensor and also newer fuel pump.I am stumped. Any help greatly appreciated

Did you replace the fuel filter ?
My 99, has a filter on it, so I'm going to assume that yours does too.

sounds like the problem i had about a month ago...go and see if you got any codes first if you get too lean on banks 1&2 most likely it's your fuel filter like i did

hot tip....wear eye protection along with something to cover your mouth gas in your face isn't fun and doesn't taste as good as it feels
