Thanks everyone for all the advice and great tips.  Will check the tank pressure, vent lines, potential debris, and fuel pump. I know now that I am working from pump back to the tank.  All is good from pump to and through the carbs.  This has been a good exercise for getting my mechanical diagnosing skills back on track.  I do have a spare electric that I could check too.  Back to the garage today and will keep you all posted.
Grateful in Ocala!

Many years ago when I was working at Bailey's, there was a fellow with am MG that would run almost all the time.  He had a problem getting up the hill to his house, though.  I fussed with it for hours, messing with the ignition and checking the carb setup.  It ran fine in the shop, revved easily, test drives around the block were fine.  The big test was heading up this one street towards his home in the foothills, a long steady incline.  It would start out just fine, but slowly lose power going up the hill until finally sputtering to a stop.  After a few minutes, it would fire right up.  After a few of these longet test runs, I thought I had it figured out, took the rubber bumper B up the 45th South test circuit.  Same thing.  I coasted to the side of the road, quite perplexed and frustrated.  I wasn't sure what to check next. I thought it does have gas in the tank, right?  Went to check.  As I started to remove the gas cap there was a HUGE rush of air into the tank.  Replaced the cap, it fired right up and I drove it back to the shop.  We fixed the blocked gas tank vent plumbing, and the problem disappeared.
