Circulation pump only running for 5 minutes

Can you give more details? What model controller? Is it possibly triggering the overheat protection? Highly likely if you have the fluid in the panels not circulating, if it is sunny out, you may be well over 250F in the solar loop.

It is a Chinese controller, looks like one of these. http://www.shuangri.com/en/product.asp

We ran it cold and hot today and the same with the pump cutting out. we got all of the air out both times, it seems to me that the controller is deliberately cutting it off after 5 mins.

Hmm, I'm not familiar with that one. I see if has all sorts of functions, my first impulse is it is a timer or protection setting, but I can't really make any guesses. Sorry.

Which pump is running?

Do you have all the sensors wired?
