2010 Nytro XTX Issues

[Kaleharrison95]

Hello,
Bought a 2010 Nytro XTX about a month ago, very good condition, looked very well maintained and taken care of even though it had 19,000kms on it.
I took it on about 3 ride totalling 240kms since i bought it, and on the 4th ride while doing about 60km/h across a powdered covered lake the whole sled just kind of locked up and shut down. No noises, no lights on cluster, oil is full and so is coolant.. primary moved a little at first but now wont move, took belt off and towed it home. I checked the cluster for codes and they are as follows:
12 - Crankshaft Position sensor
15 - throttle position sensor
22 - intake air temp sensor
30 - oil pressure dropped
43 - fuel system voltage
46 - snowmobile system power supply
81 - grip warmer
84 - T.O.R.S.

Any ideas? Where to start, what to look for. Im feeling im going to be in for a complete engine tear down. Has power, just clicks when trying to start it because primary wont move.

Are those stored codes or active.
The only time I ever saw one of these engines lockup was because of a stub shaft bearing failure. Check that first.

they are on the 61 screen, but that is good to know. The guy i bought it from said he just replaced the stub shaft bearing last year.. maybe he didn't do it very good. If that is what let go, can i expect other internal damage or is that just a replace that and go again?
