Problem solved; thanks for those who posted in past.
Issue was quick connect hose was loose (Part of 4 quick connect hoses from loader), carefully cleaned, and reattached the loose one, and then each of the others.
Will moniter in the future.
Saved long trip to the dealer and a rental in the...
Loader will only go up halfway to full height, no alarms, or codes, everything else working fine.
2020 Model, 4 wheel drive, loader and gannon, has 250 hours on it.
