Hey guys while running my motor yesterday it was cutting out/jerking on and off the entire time I was running. This is like what it was doing 3-4 months ago and new plugs seemed to fix the problem. If it's my plugs again what could be causing that and what can I do to fix it? Thanks

A better description of your motor would help. Is this carb or efi, what model?? Look at the tag on engine bracket.

What fuel maintenance items have you addressed so far? Sounds like lift pumps are shot but could be a fuel restriction, failing high pressure pump or pump relay. Confirm these items and as last resort have the injectors serviced.
