Engine dies unexpectantly

[RzeroB]

After reading your story, I, like @Dakota , noticed that there seems to be a relationship between the incline angle of your car and the problem. Therefore, I would investigate your carb and in particular your float settings.

   Perhaps the issue is what the off road folks experience that necessitates spring loaded needle/seats https://www.edelbrock.com/off-road-needles-and-seats-0935-qty-2-1465.html

@Bullitt- that's interesting... I may install those either way.  Thanks!

@RzeroB I took the carb off and apart last night and I did find the floats to be a be high, meaning the gap was less than 7/16".  So that is one thing.

Took the carb off and and apart, and the floats were set (by me) a bit high, less that 7/16" so maybe it's been flooding?  Also the manifold floor had fuel (wet) in it, but it was "orange"; I am thinking the color is due to the stabilizer I have put in with the fuel... it did not have much of a gasoline smell at all.  The air horn gasket was dry but all the other gaskets were wet.  Would stabilizer or other additives/boosters seep into the gaskets?

I am setting the floats (again) and putting in new gaskets, and the off-road inlet needles that @Bullitt- mentioned and see what happens.
@MoparLeo mentioned fuel pressure... has anyone with an Edlelbrock had issues with a stock type mechanical pumping making too much pressure for the carb?
