    review when last tuned. may be due. i am guessing it turns over? do manual test for fuel pump. turn key to start but stop just before it turns and listen. should be a short whirring sound. this is your pump priming the line. should last 2 seconds then cut out.
    rec. fuel system clean. ethanol treatment to 1 tank premium. possible build up in fuel delivery, and combustion chambers.
    should get diagnostic run to see if any other issue you should be aware of.
