New Clutch No Power now at Random

[BigOlDog]

Afternoon hope everyone is well, new here so thank you for having me!

2012 KW T660 w/ISX, 10 speed Eaton. Put a new clutch in the truck and now at random times the truck just falls on it’s face, no power. Feels like something is holding it back. No problems with pulling or power till after the new clutch. Cruise control won’t maintain when set and power is lost nor can you float the gears as the RPMs just fall right off. Any guidance as we aren’t getting codes and we can’t log the data to check things as it’s so random.
