It could be a number of things. You indicate that it has been doing this for a long time. You probably need some good tuning, but the initial problem sounds like a plugged fuel filter, weak fuel pump or a plugged catalytic converter. You are much better off having us do a diagnostic and inspect your vehicle. Then we can give you a detailed list of things you will need and you can prioritize what you want to do. Give us a call and we can discuss it.
