An exhaust leak would not stop after a few minutes. Sounds like you have a choke problem.
Why is this question not asked...................why is my 2004 ford escape spitting and sputtering .
The teleblock spell usually lasts about 5 Minutes, In that time you must try to escape by running, or else fight to the death.
Exhaust valves open at the appropriate time to allow the burnt gasses to escape.

I believe on your exhaust
They can escape by jumping over fences or running into them

You should have the exhaust system checked. If one or both catalytic converters are getting plugged up it will cause the exhaust to back up and eventually shut down the motor. Make sure your oxygen sensor is working properly. Take out the oxygen sensor to let a little more air escape and if it improves the motor function then you know it's in the exhaust. Have your timing checked and fuel purity (dirty gas tank or filter).
If the sputter dissipates when the engine gets warm then a portion of the exhaust manifold is not tight against the engine block and is letting exhaust gas escape until the metal heats up and expands, if no then you might have a break in the exhaust gasket. Nothing that will harm the car or keep you from passing a smog test but annoying for sure. In my case the last bolt on the end of the manifold broke for some reason and caused the same sputter, I ened up removing the bolt and replacing it and the sputter went away. Good luck
You Start Running!!!!!!!!!!
