WHY DOES MY DIE AFTER I REV IT UP?

1999 Ford Ranger • 260,000 miles

I've redplaced the sparkplugs (top&bottom), wires, coil pack, and crankshaft sensor. 4cly 2.5 it idles ok but if rev it up a little it idles rough and slowly returns to idling ok, but if rev it up alot and let it return to idle it dies. VERY Frustrated. PLEASE HELP.

Do you have a check engine light?

Lets check the fuel pressure and test the throttle position and mass airflow sensors
