2006 KW t800 isx15 CM870 power loss

[ahrenb]

Took the truck for a 30 mile roundtrip road test. I had insite hooked up with engine and sensor parameters recording. No issues during the road test at all. Fuel Shutoff Valve stayed open the whole time, fuel pressure minimum was 253.6, maximum was 285.7.

The route included stop and go, highway speed, and pulled a 4.5% grade hill for a mile. Hauled a lowboy 3 axle behind me for weight.

The only things that really stand out is my battery voltage had a range of 13.3-13.75 which seems a little low to me but it didn't drop out.

I'm just stumped. I'll try adding the data monitor printout here.
