Just installed a new kitchen faucet. It makes a gulping noise, and loses pressure once it's turned on, and the gulping continues for as long as the water is on. Any quick fix to this problem?

It sounds like you have debris inside the Aerator, remove clean and install the Aerator, see the image below, good luck.

Can you give us a brand name? One handle or two knobs? Can you describe the noise better? What does the flow do when the "gulping " starts? Does it still do it with the aerator removed?
Back to you, Tom
