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?
