Once I let it set for 10-15 minutes it will start up and run fine for a while, however after several miles it stalls out again. Does any one know my problem? Thanks......

Fuel lines close to headers, no return line etc, can cause our ethanol laced pump gas to boil at a lower.temp. My hemi had similar symptoms during hot summer months. Shaker base kept the heat in tbe lines too. Return line with vapor separator solved tbe problem. Just a thought.
