I have a non turbo talon that would start and run fine when cold but start to sputter while cruising and surge and rev up uncontrolably at idle before dying. If i let it cool down a bit I  could drive it again a short distance before it would happen again.  I could also keep the car going in first gear (5 speed manual transmission) if i didnt have to come to a stop. It sounds like it's running on only one cylinder.  But when it cooled down it start and run fine.  It would never overheat either.  There was just a certain distance or time you could travel before it would start to miss. I drove the car like this for awhile and seemed to just get worse over time. What should i check? ECU maybe?
