Exclamation Engine dies after revving at 2000 rpm for 20/30 sec?

95 f-250 7.3 219,000
Engine idles a little rought but after 20/30 sec of revving at 2000 rpm the engine will die. It takes about 5 to 6 cranks for it to start back. But when the engine is dying out u can give it more fuel and it will revv up but will eventually die.
I have replace fuel pump, cleaned fuel bowl and the pice on the side of the bowl, replaced all the rubber lines and changed IDM with a friends. Any thoughts?

Have you tried monitoring the fuel pressure at the shrader valve on the fuel pressure regulator (driver's side of the fuel bowl) while this is going on? Use a 0-100 liquid-filled gauge if you can get one. Does it do it on either fuel tank? Cheers!

It should be at least 40 psi with it running. You are looking to see if the pressure drops off as you're running while revving for the extended period. It is a two-stage fuel pump and can have the high side fail (my 94 would sit and idle, but die under load similar to yours). Cheers!
