Sled was running great at elevation but once down in the valley bottom it was sputtering. Soon afterwards blew lower crank bearing. Arctic cat warranty for a new crate motor and new primary . Took it out with new motor and clutches. Ran great at elevation but coming home same problem . Sled has 5000 km on it and has run flawlessly since day one . No codes flashed . Worried the sled will nuke again if I run it as is . Any ideas?

Did the barometric tube get plugged or pinched on the ecu?

There is no alert to a oil pump failing, would think the ecu would let you know it cant get to desired rpm. I am assuming you are talking about a c-tec motor with an electric oil pump
