Randomly shuts off

To clarify, it was running perfectly fine, and then the AFR gauge went instantly lean and it shut off. I put in all new fuel lines, fuel sender, steam cleaned tank, fuel pump, fuel filter etc, so everything fuel wise is brand new and it ran all last summer without an issue. So I don't think it's a clog in the line. Also I have a fuel pressure gauge on and at idle it's making about 6 PSI. When it died yesterday the carb was empty, when it works I checked the float levels and everything carb wise is perfect. But yes the lines are all rubber hoses from tank to supply line and supply line to fuel pump.

So what is it we are working on?

1928 Hemi Farmall?



1939 Flying Pancake?

LOL its a 73 dart swinger with a 360 I built last year, headers, Holley 650, aluminum heads etc. All the emissions controls were disabled, and it has a vented cap. The same fuel pump has been used for the past two years, but its possible that's the problem. I have a manual so ill diagnose that in the next few days.

It's a solid roller, but I've adjusted the lash not too long ago, and its right where it should be. Lunati wants 16 thou intake and exhaust hot, so that's what it's set to.
