Your car seems like it is going to die while you are driving?
it could be a wide range of things, depending on how its acting, if power is fading in an out and eventually dies out, you may have a bad fuel pump, and/or clogged fuel filter, otherwise you may need an oil change if your not getting the power your used to, then theres also the battery, if your electrical power and engine power are fading in and out, you may have either a bad battery and/or alternator, another thing it could be if its just the engine power could be bad spark plugs, and/or bad dristributor or spark plug cables, other than that you'd have to ask a mechanic, because as i said theres a broad range of different posibilities. hope this helped :)
