Has anyone been able to do something to mitigate this requirement of
having to have the boost pump on at altitude?  

I've had some ideas put in my head by a good friend of mine like: What
is the good of having mags or anything else that makes an engine run
without the battery if it's just going to have a fuel starvation problem
when the lights go out...

I'll continue to look through those posts, but I'm not finding anything
that would speak to this directly.

Thanks
Kevin
