Engine dies going uphill or highway speed

[jameschump]

Please someone help me. I have been wrestling with for a few days. So I have installed a new $400 carburetor and fuel filter (4.2 liter) because engine would die when stopping. Now I am having an issue with the engine sputtering and then dies when going up hill or driving for about 5-10 minutes or so. I have gone through all the vacuum lines and they appear to be solid. I also changed the oil, plugs and wires as well. This issue never happened before and I cannot figure it out. Every time I think I have it and I take it for a test drive out on the road, I end up having to push it off to the side so I'm not blocking traffic. I have read through dozens of other forums, all saying the same things but none help. Thanks
