Hi Chris and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, not sure if the 2010 is year or model. ...gas or diesel?

Still, it would appear to be a fuel delivery/starvation issue (most likely) or electrical/ignition (least likely particularly for the gas version). Proposed preliminary tries (if have not been done):

  • • re-clean the fuel path, drain the tank and replace again with fresh fuel;
  • • check the air box and air filter/element;
  • - ensure tight/correct fit;
  • • verify fuel is reaching the combustion chamber;
  • • check the battery voltage when revving for potential over charging;
  • - if overly high, try/run with the regulator temporarily disconnected.
