Zone gradually loses pressure

I've got one zone out of 8 that starts off with perfectly fine pressure like my other zones. The sprinklers then slowly lose pressure over about 5 minutes until they are a low constant pressure. I cannot for the life of me figure out why!! I understand low pressure to start or no pressure, but why would the system lose over time?? My system is pressurized by a local neighborhood pump and all other zones have full pressure.

Can anyone share a thought or idea?
