UPDATE:
Today, both the power company and an electrical contractor were out. The power company lineman installed a monitor at the lines feeding my house. They will monitor it for approximately a week to determine the cause of the voltage drop.
A bit later the electrical contractor also came out. I contracted with him to replace the entrance service, from the mast, to a new meter plug, and a complete replacement of the main panel, with an upgrade to a 200 amp service. They are also going to install a surge suppressor in the new panel. The surge suppressor also includes a $75000.00 rider for my home owners insurance.
For those who worried about me attempting to do this on my own, I am ever thankful for your concern. I think it was in a Dirty Harry movie - "A man's got to know his limitations." Well this one certainly was above my limitations, and both the wife and I are feeling good about this investment in our lives.
Once again, thanks to everyone for your answers, input, and concerns. It's what this forum is about for me.

Bob, Thanks for the intelligent and reasoned story about your situation. I like to hear about people taking an in-depth interest instead of just "call an expert". There are plenty of cases of supposed "experts" not nailing down specific problems but charging you plenty regardless! In this case, the final verdict is not in yet?
A friend had a low water pressure situation at his residence that was an elusive problem. He finally tracked it down to an undersized hole in the plastic water main upstream of the water meter. It was one of those neighborhoods where new houses are connected to the existing pressurized main with a saddle tee, then they drill through a ball valve to make the connection. But the "experts" drilled too small! And it took years to track down the real problem!
