Fuel Pump Issue??

So quick info, on my 2011 outlander max 800 its been rough starting at times and even hot starting its been stubborn, got no codes and it sputts and stalls once in a while. We had it up in the mountains last weekend and it lost power, it would idle but not pick up unless I pumped the throttle, it would go for 10 secs and loose power, pump the throttle and it would go, I performed this for 5 miles and got it back to camp. It still starts but its sometimes unhappy lol. I am thinking fuel pump???:th_smiliepullhair:
