When I’m reverse and under power like if backing up a steep hill, it hesitates like fuel is intermittently spitting gas, goes in and out and has no power. It must be a fuel problem?  What would cause it to pulse fuel in reverse only ?

I believe that is actually a  Hisun HS700UTV Crew (same as the Coleman UT700). They have a 10 MPH limiter for reverse gear--If the vehicle (or its rear wheels) are going over 10 MPH it will cut fuel and sputter. The same black box is used for the seat belt "safety" feature...

      Just picked up a Hisun 500 that had shift issues (corroded fan gear) which I fixed. It also didn't seem to be running smoothly then all of a sudden it got worse. It seems to miss on both idle and when pushing the gas pedal to the floor and doesn't seem to be running at full power. I've been working with a local person who is walking me through some steps, but I'd like some input from this group as well. What I've done:
      - drained the fuel tank and replaced it with 93 octane fuel and added heet to help with any water problems.
      - replaced the fuel injector.
      - disconnected the battery (several times) to allow the module to reset.
      - set the valve clearance, both intake and exhaust, within specs ... intake was tight but exhaust seemed fine.
      - replaced the battery.
      - replaced the O2 sensor.
      Nothing has helped. Not sure what the next steps are, but would appreciate any expertise that can be offered here.

      Hi
      I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

      Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load.  Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out.  It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature.  I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter.  No check engine light.  I don't have a code reader for this.  Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking.  I've changed the oil since then twice to clear and clean everything out, and it seems to be good.  Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77.  What should I try or consider next?

      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.

      spits fuel from breather hose into the air cleaner and then down into carb.  What’s causing this ??
