If it's a single lever/handle faucet then the cartridge in the faucet (the working mechanism) may be the culprit. Other possibilities are a clogged faucet or possibly a problem with the shut offs under the sink. The first thing to do is to turn the water off to the faucet then remove the guts then turn the water back on to see if you have any flow.
