Fuel Pressure Loss

[leftysdad74]

88 ranger with the 2.9 has and holds 32psi fuel when first cranked....at exactly the 5min mark starts dropping until it gets so low, it cuts off.....I can wait 2/3min, crank it back, it's right back at 32 for about 5secs, then drops again until engine dies....I inherited this truck and looking for a place to start....no check engine light is on while it runs good for the 5min , thanks in advance

Start with fuel pressure regulator. Its the easiest fix 2 bolts and insert it Might have a bad diaphragm
