1991 Chevy Silverado V8 Two Wheel Drive Automatic

I have this 1991 Chevy pick up, Eng size 5.7 v8.
The problem is that it will just cut out (stall) when accelerating from a stop any where from 0-35 mph. It will idle OK but, I put it in drive and press the gas and start moving and it will just quit. I know it could be a few thing causing this problem I just want to know if some failures are more common than others and a good starting point in trouble shooting.

Thanks in advance

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
