I have searched old posts and read other groups and I must have a unique Cobra. I have owned 7 years and have not encountered this problem yet. Driving along at about 40 mph. All of a sudden no acceleration and car now decelerating. I have not checked fuel pressure yet, however I traced all vacuum lines and emmissions components and cleaned and made sure connection was good. Changed gas cap, and re-installed some of the many duplicate emmisins parts that I have and same thing. Pulled 3 plugs and checked and nothing out of ordinary. Does anyone have a vacuum hase diagram for a 96-98 Stang? Since the V-6, GT, and Cobra use same charcoal cannister hose routing must be the same. I don't think this is my problem because the hose that runs to the intake manifold has been undone in 2 places for at least as long as I have owned the car. Please post any info you feel will be useful to me. Thanks, Alan.

If it stopped running and now it won't start, it sounds like fuel to me, either that or electrical.

Can you hear the pump prime when you turn they key on (don't crank it, though)

It does get fuel and spark. No error codes. Screwing with it for 4-5 weeks due to tight budget. While crawling around underneath I have found many more minor issues and repaired them. Just wont start. I did blow out a catalytic converter thru the exhaust. Is there a chance it could be causing a no start scenario?

Absolutely it can be causing the no start. I was thinking clogged cats anyway. Still, check your fuel pressure, cheaper than exhaust. Just because it's getting fuel doesn't mean it's getting enough fuel.

Drop the mid pipe and try and start it. A vacum leak from something like the charcoal canister wouldn't cause this and besides a CEL you probably wouldn't even notice it.
