How many hours on it? Mine does the same thing, and I am sure it is because when I did my 840 kit, I think I might have the valves a bit to tight. It runs good but always stalls when I stop, but starts up and idles fine afterwards. If you have alot of hours on your machine it might be in need of a valve adjustment.

is that the only thing it could be runs great except for this
i was having a similar problem and it was cause i sunk the teryx in water and got my coils wet did that for a full day run great just wood die if you stopped or braked hard or slowed down fast. I took both coils of and blow dried them for a while to get them nice and dry. Seemed to work stopped happening after that.

P.S. i left it park for a week to and the problem just went away.

Idle is controlled by three things.

Crank position sensor, ECU and Idle speed control valve.

CPS tells ECU how fast it is going and then the ECU tell the ISC valve how much to open.

The throttle plates are closed during idle, idle air goes from the air box thru ISC valve then in a passage under the throttle plate.

Your issue may be your ISC control valve might be just dirty, you can take it apart and clean it, might need a new one.

There is a idle speed on the throttle but we only mess with it when we do engine kits.
