So i was on my way home from a meet when all the sudden my Car starting acting like it was running out of gas at 75 MPH. I would rev it and it would slowly rev, etc. So i put some gas in it, and it continued to die on the freeway. At one point i dropped it into third at sixty and stepped on it and the car did nothing for about 3 seconds then all the sudden the car kicked in like nitrous would for example. Is my fuel pump going out?

+ 1 on the fuel filter. mine started to go. when it got hot, the car would die, if i let it cool down, i could drive a bit again. another possibility may be engine bearings. something like that happened to me and thats what it ended up being. hows the oil pressure?. hope its not though! REBUILD!

Most likely it is your fuel pressure regulator. That sits right on the fuel rail and controls how much fuel pressure their is. Has happened to me on both my 86 GT and my F150. I would start there before replacing anything. Someone said check your fuel pressure--do that if you can. If you can't, change the fuel pressure regulator. They are about $35 at Autozone.
The car has an Aeromotive FPR.
At idle Fuel Pressure is 28
And at WOT 32-24
How do i adjust the Fuel pressure on the Regulator?

when mine went, it started making a different noise too when i turned the key forward. i don't think you can really go too big with a fuel pump, and they isnt really much price difference... so i'd def. go big if you're planning a power adder. i have a walboro 155 and its worked good for me. but maybe someone can correct me if i'm wrong on any reason why not to get a bigger pump?.

When my fuel pumps have gone bad the car (or truck as the case may be) would barely run or die completely.
Ok so the car doesnt die anymore but like i said it hasnt been raining here, and when it was raining, the car would die. Weird i know.
The car is idling anywhere from 950-1200 Rpms And fuel Pressure is 27PSI at idle, and 34-36 WOT.
Shoud i give the fuel filter a try? How do i adjust fuel pressure on my Aeromotive regulator?

Read through this thread for almost same problem that I'm having. Your fuel pressure sounds low to me, though....

A fuel pump can read just fine when cool and no load on it, ie at idle. You have to test it when warm and load on the engine. Hook up the gauge and drive it down the road with the gauge out from under the hood so you can watch it. If it drops under load, then there is your problem.
