Truck cutting out

[jameshill]

I have a 1988 GMC S-15 and When ever I give it more then half throttle the engine cuts out like its not getting enough fuel. The problem is IDK how to check that so if anyone can help I would appreciate it.

When was the last time the fuel pump has been replaced? This sounds like the pump is failing. I say replace it ($100) fix, replace the fuel filter at same time. 

  Also thier is a small metal filter located inside the carburetor where fuel line go into. Un bolt that, remove that filter. It's not really needed and tends to cause problems. 

  I have replaced my fuel filter in my S10 when it was doing what you got and it solved the problem. Easy way is to unbolt all 6 bed bolts and use Jack's and 2x4s to raise bed up enough to swap out fuel pump. YouTube has a video
