From the way you phrased your question I assume you mean cold only - that you still have hot water at the faucet and cold water elsewhere in the house, so a general water failure at hot water heater or such is out of the question.


Common possible reasons:


1) cold pipe under sink or in wall behind sink froze - bear in mind if you open the kitchen cupboard doors under the sink up to house air to thaw it, check under sink and on floor and area under it (at next floor down if any) and area outside and under that sink frequently for leaks as it thaws, because if it froze solid under the sink it could have burst a pipe or fauceet washer, so when it thaws you might get a leak. In prolonged cold weather outside (commonly below about 15-20 in poorly insulated houses, below about 0 to -10 or so in normal houses) it is a good idea to keep the kitchen cabinet open to air - keeping in mind pet and child safety of course.


2) someone turned off the shutoff valve under the sink for some reason - or small child playing


3) if a slow progressive decrease in flow, could be buildup of iron or lime or such in the pipes, choking off the flow - or if accompanied by a shot of rusty or dirty water could be some accumulation broke free and clogged the line


4) very rarely, with some faucet types, if an internal component fails (generally with single handle faucets) hot or cold water can stop flowing.


5) rarely, someone shoved something around under the sink and kinked the line to the fauceet enough to pinch off the water flow


6) rarely, and again usually would be progressive drop off in flow, a plugged up under-sink water purification unit can do this. Some types have an automatic shutoff when the pressure across the filter reaches a certain level, so in that case you would get a total shutoff without warning. Commonly that type has a filter bypass valve at the top that lets you turn water back on till you can install a new cartridge, though of course the water will not be filtered/purified during that time.


7) rarely, the "stutter valve" in the separate spray nozzle hose gets stuck in some models, so it diverts the flow to the spray nozzel even when the nozzle is not in use. (Some models have this, others just "steal" the water from the faucet to water runs in both at the same time). Try using the spray nozzle a few times - might free it up. Sometimes requires turning shutoff valve under sink off, then opening both faucet and spray nozzle and reopen shutoff with themm open ot free up the "vapor lock".


For #3 and #4, if you shut off the shutoff valve, disconnect the piping to the faucet, then turn the valve back on with bucket or such to catch the water, that will tell you if the problem is "before" or "after" the valve, which will narrow down the possibilities.
