Does it just CUT OUT or does it sputter, bog and start dieing on you. Alleyoop

Hi asumblin. Does the engine actually shut off and then you come to a stop or does it start running when you let it slow down a little? It could be fuel starvation.

Well that is Fuel Problem, it could be your Fuel Pump, or it is running Lean and starts to starve out at high rpms. Check your Diaphgram for leaking or rips in the rubber. Alleyoop

I have an idea. You have two outputs on your intake manifold. Take the top one and run a 3/16" good rubber hose to the pump. Put a Y connector on the other lower nipple and run the rest of your hoses off it. You will get more vacuum to your fuel pump.
