Rotax 912is ETPU Fault Unexpected Stall

I had an engine light illuminate and i pulled the fault and data logs. I see a Failure with ETPU Test , Unexpected Stall. I have looked at both CPS1&2 sensors and swapped them around to see if the fauilure would switch to the other lane it had no effect. All spark plugs & connections are good. Anyone know of anything to try and test next?
