It looks strange. I ran my pump for a whole day today and it stopped running an hour ago,no pressure and no flow. But it's working well after I turned it off and waited about 40 minutes. I didn'd do anything trying to fix the pump up. what's the reason? Maybe it just needs a rest...:) Does anybody have the similar experience?

Maybe something got hot, even a component on a circuit board, or inside dust insulating an electronic component; if it happens again, see if a cooling fan helps or avoids the problem. For sure, no one can fix an intermittent problem when it's NOT occurring.

Anon 1,

please check the minimum and maximum pressure settings, may be, your pressure drop is during this time out of limits. Or You have set in the software a shutdown after a given time. What type of pump You are using?
If nothing like this, Your machine needs to be serviced....
