Why does my Polaris Sportsman 570 EPS Offroad Vehicle engine keep stopping or losing power?

J
John LittleAug 23, 2025
If your Polaris Offroad Vehicle engine stops or loses power, several factors could be responsible. Begin by checking if you're out of fuel. If so, refuel, cycle the key to the ON position three times for 5 seconds each, and then start. Inspect the fuel vent line for kinks or plugs and replace it if necessary. Also, check for water in the fuel and replace it with new fuel. Inspect, clean, and/or replace any fouled or defective spark plugs. Ensure that you recharge the battery to 12.8 VDC if the voltage is low.
