my car has a new battery but it will stall and sometimes not start unless its jumped

or sometimes it starts with no problem I need help and don't know what it could be if its the starter the alternator or the throttle body that is dirty... if you have any answers please help.

If it sits for a period of time and it's a good battery... it may. E a parasitic drain that's causing it not to start. O don't know why that it would stall why driving unless the vehicle alternator is not working or the cam sensor, if you have one on that vehicle, is not functioning properly. I'm not sure why the TB would keep it from starting or drain the battery, only that if the TB is bad it may stall. I hope you find out a good answer before spending good money
