98 chrysler t&c starts then cuts out

the car either will start and cut out after a few seconds or just not start at all; if you give the dashboard a smack (or two) above the instrument cluster it usually will start and stay running. the car is becoming less and less reliable. how do i fix the start & stop problem; if i need to remove the dash please include instructions on how to do so; thanks!!!
