Noises problem
1997 GMC Safari 6 cyl Two Wheel Drive Automatic ? miles

My GMC Safari has had a problem for many years and has been in and out of the shop for the same issue. The van will work fine for a while and then as we are driving along it feels like it is starving for gas. the MAF sensor has been changed, the fuel pump has been changed, and wiring has been changed I have had to family friends to dealership to AAmco, nobody can recreate the issue what do you recommend that gets checked? I am really at a lost! when it runs it is a great van do not want to get rid of!!!

this sounds like a fuel pressure regulator issue.
