I resolved the Cycle Analyst intermittent shutdown issue described in and earlier post on this forum: Cycle Analyst shuts down randomly and infrequently.
But I continue to have an issue that I'm pretty sure is not related to the Cycle Analyst, where the power delivered by the motor suddenly drops in half while climbing a 2 mile steep (1500 ft rise) hill. If I stop for a few minutes and restart climbing (I don't reset anything, it stays on the whole time), it works at full power for a little while (several minutes).
It seems to only happen while doing such a long continuous climb. It doesn't show up when I do a bunch of shorter (but equally steep) climbs followed by downhill or level travel.
I did check all the Phaserunner v2.0 settings and they seem correct based on the V2.0 Manual and some earlier feedback from Grin Tech. I will post those at the end of this.
I did check the CA diagnostic view while the sag was happening and:
Now when this sag happens (power drops to 600 to 800 Watts or so, from the peak of 1500 to 1750 watts when there is no sag) I'm going up a twisty narrow steep hill. I suddenly have to pedal at a level that is pretty strenuous and pushing me beyond what is my theoretical max heart rate. I also have to pedal to at least get myself to a safe place on the road so when a car does come by I'm not a sitting duck. Also I don't have the wherewithal to do much else than just try to get to a safe spot. So I'm not able to do much more checking of the CA than glancing at the diagnostic view.
The setup is:
My theory is that there is something hitting a limit in the Phaserunner settings that is cutting in at the point of Sag. Which mean something is not set right as I'm pretty sure I'm not at the limits of the Motor, Phaserunner or Batteries. But of course I could be wrong...
Would love to hear some suggestions on how to debug this or how people may have fixed something like this before. Below is the Phaserunner setup.
Thanks!

I did check the CA diagnostic view while the sag was happening and:
- None of the Limit Flags are set (other than the expected intermittent W flag)
- The Throttle out is pinned to 4.00V while I'm pedaling or throttle is on full during the power sag)
- It does this with PAS or Full Throttle (i.e. its not a PAS issue)
- Motor temperature has never been more that 70 to 80 degrees Celsius during the climb.

The setup is:
- Recent Crystalyte H3540 with statorade, 35mm laminations and aluminum stator core (should be able to do 1500W continuous)
- Cycle Analyst v3
- Phaserunner v2
- Two Grin Tech B5213LiM-DT 52v 13Ah 25A Continuous Output Batteries in Parallel (so 50A Continuous Output total)
- Thun Bottom Bracket Torque Sensor for PAS
- Thumb Throttle
- ICE Adventure Recumbent Trike
- Total Weight (Human, Trike, Motor, Battery, Misc Stuff): ~325 lbs
