Rzr sudden loss of power

Little background:

2008 rzr 800. Just did a new top end. Was on second break in trip at about 50 miles total. Was riding quite a bit of mud/puddles but not submerging it. After several hours was riding back to the truck and just suddenly had a loss of power. Could only go max 15mph all the way back.

At some point during the day I noticed the check engine light had come on. Did not ever notice any error codes though.

At home washed it off, removed new Donaldson filter system. There was some minor water droplets past the filter in the boot. This filter has the intake underneath the filter housing. According to Vent Racing this is where it’s supposed to be as it no longer uses the stock location between the seats. I guess with the suction power it drew in some water from all the splashing? Seems like a real stupid setup Vent Racing!

I did notice the TPS has become totally disconnected. I can only assume I did not click it in enough when installing everything. Cleaned it and put it back on. Still no change on power issue.

In idle the machine seems to sound normal when I rev it up.

Compression test came in at 150 psi. Unusual though the pressure gauge would not hold the pressure as it has in the past. It bled out fairly quickly. Not sure if this is related or a separate issue?

I’m kinda thinking it went into limp mode but not sure how to test this theory/fix it?

Open to ideas/suggestions?

Thanks!
