Default Truck looses power at random

I really need some help I can't figure it out the truck randomly looses power like the air flow is being cut off but some days it runs like a champ scan roof said an o2 sensor I replaced that and it was good for a day or so and then another code came up for a mass airflow sensor and it's still doing it after I replaced that the truck is a 1994 ranger 4x4 five speed any help would be appreciated it's my only vehicle so I'm kinda screwed

Check for vacuum leaks especially around the intake manifold

And around the intake hose after the MAF and up to the TB..

I recall one time removing all of that for some other work.. drove it for nearly for a month with no issues ONLY to find I never tightened the band clamp around the TB.. it started to give me a similar issue as a bad MAF all of a sudden.

I wanted to cuff myself in the back of the head for missing that....
