DS90 looses all power after 10 min of riding.

Hi, just wondering if anyone has seen this before and has a fix, my son has a DS90 2016, has ran like a champ, zero issues until this weekend. all regular maint is done the last 2 years, new oil(s) and spark plug, air filter. we were out on trail prob 1/2 to 3/4 throttle, and it started to sputter, and loose all top end and sounds like its bogged down but still idles no problem. what we have done so far:
-Changed the spark plug on trail - No change.
-Check and and cleaned air filter - No change (and clean as if it was just put in)
-Replaced fuel filter - no change

-checked oil - clean and at the right level.
-Check gas tank lid to ensure it was venting


I am thinking either ECM or coil?



Here is a video of what its doing:

Front Dif Noise

So twice now under hard load in 4 wheel drive I have heard what kinda sounds like a ratcheting sound coming from the front end. First time I was stuck on a stump/rocks trying to get off. The 2nd time was a couple weeks after that trying to climb a steep hill (that I probably should not have tired in the first place). This is a recent thing over the past month.

It's a 2015 Outlander BTW.

Thanks!!
