airlock or blockage from the sound of it
if it is possible to disconnect the pipe work from the tap i would then install a isolating valve(water turned off) shut of the isolating valve turn water back on then open isolating valve ,getting ready to catch water somehow and see what the flow is like,give it a good blast,check the tap clean out if required reassemble take it from there
