Hi all. I'm trying to narrow down an issue. My Mustang will start and stall out after a minute or less and then will take a few minutes to get started again but won't stay running. A few weeks ago while cruising highway speeds it would cut out/kick and backfire a bit then run fine. I've replaced the mass air flow sensor but it's still acting up. Any ideas? I'm thinking maybe a fuel filter or fuel pressure regulator. It has new plugs/wires/distributor cap that are 6 months old. Help and thanks!
