Ok, I'm about to rip my hair out! I have a 69 351w in my 57 F100. I have replaced or redone just about everything on the truck. I have a factory gas tank with no vent that I did a POR15 tank kit in. It has a new tank pickup and I bent all new gas lines. New mechanical fuel pump and a never used 600 cfm Edelbrock carb that sat on the shelf for a while. Here's my problem. I static checked the timing then set it with a light. It fired and idles GREAT. I can put it in gear and move it around just fine. When I went to take it out, I got about 1/2 mile from my shop cruising about 40 mph and it started to stutter. It stalled and would not start back up. I pulled the air cleaner on the side of the road and looked in the carb and it wasn't getting any gas. I started checking fuel lines to see if any were hot and none of them felt hot. Part of the frame rail the fuel line is attached to is getting hot from the exhaust but the line did not feel hot. I tried to start the truck again after messing with it for about 10 minutes and it fired and idled perfectly. I turned around back to the shop and right as I was pulling back in it died again. I checked the filter and it is clear, and wasn't getting gas to the back of it either. What the hell is it doing?!?!?!?
