Question: Power loss and die out under acceleration load

Rookie
Truck looses power and stumbles under acceleration and I have to slow down, put in neutral and back in drive to go again. Does good for 1/2 mile and does again. Fuel pressure is good, 30 psi at idle and steady 34 psi when power braking hard. Does the same thing when power braking but fuel pressure stays the same. Put in new computer and is NOT setting any codes. What could be the cause?

Master30 psi is low. Most of these vehicles need about 40-45. Where did you get your specs?
