lately my blazer hasnt been running right. it starts but after 15-20 minutes of driving i suddenly lose acceleration when i give it gas. i have recently replace my gas tank, fuel pump, fuel sending unit, fuel filter, and fuel pressure regulator.

i'm not a machanic so i have no idea what to look at next. any advice or suggestions?

 

Is it making any engine lights come on? I wonder if your EGR could use a cleaning or is malfunctioning. When you are getting too much EGR it doesnt like to accelerate and wants to stall. When its stuck wide open it will stall and restart no problem.

 

no all lights are off on the dashboard. how would i go about testing my EGR?

 

About 8 months ago my blazer did the same thing it ended up being the wires that went to the spider , Try wiggling the wires .
