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.

Have you tried resetting the ECU? Likely something funky happened with the IAC settings or the fuel trim.

When running rev it to redline in neutral, and shut it off with the pedal still floored. Wait 5 seconds and then let off the pedal and restart as normal

...or you can use the codescanner method if you have the codescan cables and HUD ECU hacker

      UTV Odes Ravager 1000cc - Strange noise from the back
      By Ermd ttk
      Hello friends,
      I got my ODES Ravager UTV yesterday and after a couple of hours of driving when I go downhill I heard a strange loud noise a couple of times, like a gear skipping or maybe something from the differential.
      It doesn't always happen and when it does it is heard for a few seconds and then it goes away and everything works normally, I'm worried if there could be some major malfunction or what could be the problem if someone can help me?
      Thanks a lot.

      American Landmaster TW450 Won't Start!!
      By malenurse13
      We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used. 
      The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn. 
      THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
      Thank you!
