Car all of the sudden dies

My 95 Mustang 5.0L was acting great, then all of the sudden died. Acted like it wasn't getting any fuel and if I tried to give it more gas, it would just choke out. It won't start back up until after about 15-30min. I changed the fuel filter last night because it was totally blocked - thought that was the fix. Now the car has just done it again. Is this common for the old 5.0Ls? Any ideas what it could be or how I can fix it?

The first thing you should do on any EECIV car is spend the $35 at Pep Boys and buy a Ford-version code scanner. Comes with a book on how to use it, and will reveal a remarkable amount of info about what your engine is doing. Absolutely the first place I look for any problem, because it frequently saves lots of time and trouble trying to figure out what's wrong. Indispensible. You could have anything from a dead fuel pump to a bad mass air meter. First last and always run the codes before you spend any time trying to figure out what's wrong with the old techniques. That EECIV computer is smart, smart, smart and can tell you if it's any one of a dozen sensors or controls, a loose wire or even if you have a weak injector. Only if there's no codes, then you can move on to spark versus fuel.

Turns out the fuel pump was barely operable. Should be fixed in an hour or so.

Replaced the fuel pump and now the car runs rich... really rich. What now?!?!

Check the regulator.

Yep just put a F/P in a '88 Turbo Coupe that only had 25 psi. With the new pump pressure was almost 85 psi, swapped the regulator and it settled back to 39 psi just like the service manual says.
