Thanks for the update. I might have suspected low pump pressure from your symptoms, but now I know better.
Personally, I have replaced the front and rear "main" (large) accumulators, the smaller return accumulator in the back and the pulsation dampener, and of course flushed the system. Today I chased down a small puddle to a seeping line on the rear control block; other than that its been working well.
