yeah I know where the power distribution block is

I was gonna say IAC....but it's starting to sound like the fuel pump to me too.

Just a liitle more insight on the issue:

Last night I took it for a quick spin around the block. The car never really spit and sputtered... it more or less just fell on it's face and genereally lost power above 3,000rpm. I took off from a dead stop and off the line it seemed all right, but when it got to around 2800 it started planing of and by 3200, the car would not accelerate even with the gas at 3/4 thottle.

I'm thinking it's the pump.

oops..yeah your right

Anyway, it's not a valid question anyway....I was wondering if it was an auto, that it might be a bad valve body or somethiung pulling the motor down. But then after I asked it I remembered that the car was actually cutting off too. duh!

03-04 mustang with 54 thousand on the clock, Woman driver complaint, car will run fine till it gets hot and or low on fuel. car was taken to well know shop to be diagnosed, OBD 2 said missing on no 5 cylinder, system running lean on left engine bank. Shop recommend plugs, wires, filter, general tune up, 350 to 400 dollars. Car was brought to other shop, found fuel pressure to not be what it should be at idle and under accelarateion. Problem was carefully diagnosed, checked fuel pump driver for proper fuction, checked fuel rail sensor for proper fuction, all was working fine. (The pump could not be fooled into making any extra pressure,) Tank was removed and found that when tank was assm. at factory silcone was used on the vent tubes, we all know what silcone and gas does. This pitucular car had two filters in the tank, both were stopped completly up. Whole tank and pump assm. was replaced,problem solved. Dont know if the cobra was put togather like this or not, but maybe give you some idea what to look for.

When it is hot and God forbid you run the air, it spits and sputters at an idle after the initial cutting out upon acceleration and just before it dies. Trust me on this. I know that car like the back of my hand.

Lee is supposed to put a fuel pump on it sometime. If that don't work, we'll drop the tank and have a look see. Thanks everyone for all the helpful info.

I was running out of ideas. It's a trial and error thing now. I don't like missing vert weather like I did last year.
