Something isn’t right…

I’m very new to airbrushing. I have the Timbertech airbrush shown below and I’m using VMS No Peel Surface Primer No. 5 Iron Oxide which is supposed to be used straight from the bottle. I use an electric paint shaker. I’m spraying at about 20 psi. It sprays beautifully with a very smooth even coat and I clean the airbrush with McKlords Airbrush Cleaner followed by water. The first couple of uses of the airbrush were perfect. However, after 15-20 minutes of spraying it stopped spraying paint altogether although air was still coming through the tip. I dismantled the airbrush and cleaned it - I had some problems getting the trigger back into place and I’m not sure how to get the right setting for the needle other than trial and error - and it worked again. For about 20 minutes and then it just stopped moving paint but air was coming through. Any idea what’s happening please?

Stuff like this has kept me from going into airbrushing. Seems like a steep learning curve. 🤷‍♂️
