Polaris 700xp idles fine want take throttle dies as soon as touch throttle changed map sensor and injectors has 40psi on pump could this be throttle position sensor

When it does not start spray come starter fluid into the throttle body/carb to see if it will run. If so, it is a fuel problem. Also check electrical connections for looseness.
Possible contamination of the fuel with water.

Odds are your carb needs to be taken apart, cleaned, reassembled and adjusted if needed.

"Throttle Body Control - Adaptation Aborted, Condition Exists"
Output of your ETC Throttle (Electronic Throttle Control) is out of range, possibly a bad connection from the Throttle Body to the Electronic Control Unit

The only thing which comes to my mind is that the KNOCK sensor feels some vibration in the engine and shuts it off?

I found a list that might apply. Not specific to Polaris, but general for electrical. Code 021 reads accelerator fault safety lock out inspect accelerator resistance and wiring

Here's the complete list.

Hope this gives you something to look at

I also found this list specifically for Polaris:

Two things, not enough gas coming through the carberater or a vacuum leak

turn idle/lean down a bit and see what happens, then the gas may have water,timing, carb could be a few things

sounds like your high jet in the carb is either clogged or you have water in your fuel.

CARBS NEED TO BE WORKED ON .

May be fouled plugs. If not check vent hose on carb.
