I have a Fimcoatv sprayer with a high flo gold series pump mod # 5275704 ..the pressure will rise to 40psi & then drop to 20psi & then back to 40, this cycle continues through out the spraying...

As it is a diaphragm pump some pressure fluctuation will be normal but that is likely to be more of an oscillation at the speed of the pump rather than a steady or slow cycling of pressure.
If it is important those oscillations are damped to provide a smooth noise-free pressure the design would include an accumulator.

If everything remains constant - a constant fluid intake and a constant spraying orifice and the pump running at a constant speed then the pressure would be constant and the motor would be consuming a constant current.
Clearly something is not constant. Something must be changing and cycling to cause the pressure fluctuations. I have a theory but am not in a position to test the theory myself - Inserting an ammeter in series with the motor in the electrical supply to the pump and monitoring the current drawn should show it fluctuating at the same time the pressure fluctuates. If the current falls as the pressure falls my theory is the pump intake is being restricted somehow and if the current rises as the pressure falls the pump is labouring due to outlet being restricted in some way or because there is a motor fault. It would be important to monitor the supply voltage at the pump at the same time to ensure it remains stable.

10 second in betry low

I assume "betry" is a battery? It may be time to replace the Battery, always get a genuine replacement, inexpensive aftermarket batteries don't work well.

Is your switch an "air switch" ... could be you have a leak in the hose that connects from the push button to the actuator that actually does the switching. Check it out.
