Regularly, including in the middle of my last session when it was acting up.

I tried mixing in thinner in case the paint was too thick (it was already an air paint) but that didn't seem to change anything.

I can try taking it apart and cleaning it again, but are there maybe any other issues? Would a lack of cleanliness aline explain why it starts initially then dies off?
