Have you had the engine serviced?  Sputterin' is most likely low water pressure in block or overtemp signal.  Maybe even the ECU driver killing ignition spark from not being serviced or all injectors acting like the weakest one.  Both will put your engine in "Gaurdian" mode (if it is an EFI or 4-stroke).  You would be surprised!  Find a shop that has the software and proper diagnostic equipment to make repairs/adjustments/service and I'll bet you it will run as new.  My .02 worth.  We are only 2-4 days turn around in service should you need us.
