Default 91 Mustang won't stay running

Here's my car's deal. Whether I stop at a light or am driving it it'll start to idle funny then just cut out. I will start it after one or two tries then it'll drive for about about 50 yards and conk out again. I need some ideas on a starting point to troubleshoot the issue. Thanks in advance.

Tests do them do not guess. Use bb gun approach not shotgun. This saves aggrevation, time, and money. This being said, EEC1V test, cylinder balance test, fuel pressure test. Try Joel 5.0. Do your homework or take it to a shop.

check your fuel pressure, sounds like your fuel pump is going out or your baffle in your tank has let go, if you want to do a quick test for ****s and giggles go to the back side of your stang and shake the whole car side to side, if the baffle is loose it will be loud, truly loud, not a little clunk but a big one.
