Whoa! Let's cool down a bit...
Check the Fuel Pressure regulator on the V8. If it is leaking and not maintaning line pressure, the heat from the engine could be vaporizing the fuel and pushing it through the return line back to the tank. You can check by removing a fuel line after the engine is nice and toasty, then wait about 20 mins, then remove the pressure line with the engine off. You should get a hefty squirty of fuel... If not then you've found your problem!
If not that then it could be speed sensors, which should throw an error code.
