1994 Chevy Blazer engine cutting out when accelerating

Engine Performance problem
1994 Chevy Blazer 6 cyl Four Wheel Drive Automatic

my 1994 chevy s-10 tahoe blazer cuts out when I accelerate, while driving or in park but idles smooth and if I accelrate all the way it blows a little bit of white smoke, been told it was the spider injectors or maybe the cap and rotor, or the crank censor. The check engine will come on for like two minutes then shut off does repetely. What will cause this cutting out problem? I also recently replaced the fuel pump, fuel lines and filter. The truck will bogg down and cut out on acceleration and uses more gas than it should!
