do any fault codes register? my other guess would be to check for obvious things like vacume hoses split or maybe a manifold gasket is gone, try spraying CRC on the manifold where it meats the head, if the idle changes you have a gasket leak, otherwise maybe a fuel adative could have a bad batch of fuel or a blocked injector?

fuel pump may be on the way out if there is nothing wrong with the above statement

Dirty air filter, dirty injectors or a blocked cat. And check the high tension plug leads that they are properly connected to the plugs.....sometimes they are not fully pushed home. If you ran low on fuel it could be that your fuel pump has picked up some crap which is blocking the pickup tube or water in the fuel. This will intermittently stop the flow of fuel. Good Luck.

Try checking the air flow meter. If its not working properly your car can run lean which will make it backfire.
