There's a couple of things it could be, so let's name the most common. 1st & foremost, have you scanned for codes? It'll give you a general area of where your problem is. By the sound of it, I'd always check the fuel bowl/filter 1st. Check the condition of the filter & also the fuel. If the fuel is really cruddy-looking, your next place to check would be the pickup screen in your fuel tank. The screen is known for accumilating crud & could cause these problems. There are a couple of other things it could be, but check these areas 1st & see about getting some codes.
