Help!There's something wrong with my car

It cut out like 5-6 times ! It seemed to cut out when I was stationary? And as I was driving it seemed to be like jolting/spluttering at all speeds (20,30,40,50). It didn't cut out if I gave it revs or used the choke - but surely I shouldn't be doing this when I had been driving it for an hour?
P.S (Sorry for my lack of knowledge!)
