My Audio-Technica AT4033CL mic worked great up until recently. it has been cutting out and not picking up sound constantly, i have to tap it in order for it to pick sound up again, sometimes it stays working for a few minutes but mostly it just cuts out again after a few seconds. Please help! thank you!

The most common problem at these cases is a loose of the phantom power. Take a closer look at all the connections and check that the phantom power supply voltage is enabled at the mixer. If it's possible check with a multimeter that you have 48V DC at the 2 - e pins of the XLR connector.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
