try ethanol treatment in fuel system. ethanol build up could be effecting fuel delivery. 1 tank premium with treatment. result will take drive time to show. review when last tuned. may need to pull spark plugs and regap or replace(rec. premium). examine ignition cables. these are things u can do your self. if prob. persist than take to a mechanic.
