Almost like it's losing it's "prime" like the lines are leaking out and air getting in them, then they have to fill up.
any ideas?

What is the length of hose between your checkvalve and your nozzles? Do you have a T fitting that splits the water flow to each nozzle? If that's the case, I guess that the line is emptying itself slowly because of engine vacuum.
I used two solenoids to counter that: one for each nozzle. Those solenoids are activating using a boost switch that needs 7 psi of boost to open. This way, I'm sure that the pressure stays into the lines and I don't need to worry that the liquid slowly drip into the cold side pipe when the car is taking a nap.
