I talked to one a few days ago, I have a 2009 mercury mariner 6 cylinder Mechanic's Assistant: What is the model of your '09 Mercury? Yes Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? Nothing yet because I noticed that the oil light will come on first, just if I'm stopped then shortly after the engine light comes on and it starts misfiring Mechanic's Assistant: Has your vehicle stalled? Has anyone run a diagnostic test to pull the trouble code? I have but I don't know what they all mean but the recurring codes are #2 cylinder Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? It runs good for about 30 minutes then the check engine light comes on and it starts spudderin but doesn't die it just shutters

A misfire will cause the shuttering feeling you are getting. More than likely you have a bad ignition coil on cylinder #2, but if you have more than one misfire code, it's possible there is an issue with a vacuum leak. Generally though, if the engine starts fine and runs well for a while, it's a coil failing when it gets heated up. If you can list the codes, I can provide a more detailed answer for you.
