stock stang 93 5.0 boggs out at 3500

[Cloneman315]

Anyone have any ideas?No cel lights or codes,bone stock car,Changed plugs,checked cap rotor ,wires fuel filter etc,Also checked fuel pressure.Car starts right up idles well,car pulls great till around 3500 then just boggs out bad,wont take any pedal.I cleaned the mass and also unplugged it with no luck.any ideas?I am guessing I should still try another mass air?But by unhooking it shouldnt the car see a default a run correct or a little better?

Can you hook up a fuel guage and monitor while driving? I had a pump that had good pressure at idle but would stop supplying volume needed at higher rpm.

does it just hit a wall and stop pulling? or does it clear out and pull thru ?
