I hope it made sense. Consider the recommendations I quoted from Continental, Cirrus and Advanced Pilot Seminars to run the low boost pump above 10,000'. Temperature under the cowling, fuel temperature and density altitude are all factors. If your firewall fuel line routing or temps are just a little higher than some other applications it could easily cause your problem. My Legacy has 1/2" fuel line all the way to the Gascolator and a engine pump shroud (from Lancair) with a blast tube and I still had the problem. Low Boost solved it for me.
