We all feel and share your frustration with your car. If you have good compression then there is nothing wrong with your valve clearances which in any case too loose/too tight would not yield your symptoms. It is highly unlikely that anything is wrong internally as loose bearings or loose chain again would not give those symptoms.


I believe Owen-Dyneto suggested putting a temporary "pony tank" to feed the carb by gravity eliminating any tank/lines/hose/filter malfunctions. I have not seen you try it. Although you scoped the tank that does nothing to insure there is nothing anywhere to restrict the fuel supply. If this does not improve the problem then at least you know it's not a fuel problem considering the carb has been ruled out.


Your malfunction may have nothing to do with coming to a stop, the conditions of out/back are different. Coming back you are going uphill, the fuel must be pumped uphill and the engine is straining more. Any one of those can be a primary/secondary cause. Engine straining especially with old motor mounts can twist the engine causing the flex hose to kink or expose an air leak, you mentioned once, I recall, that your fuel pressure went to zero.


Years ago I had a '40 120 with 20,000 miles that ran perfectly until I went up a steep hill. Problem was very fine silt that clogged the screen in the FP, after the stall if I let it sit 2-3 minutes it would start and run all day until the next steep incline


Good luck.
