Problem has been identified ! I believe the pump 'pressure switch' is the issue.
Pressure switch is mounted on a 1/4-in tube near the pressure tank.
I was able to trouble-shoot the cause and solution from this website.

I have attached a picture of my pump switch. The 1/4" pipe I tapped is shown below the switch box.
They stated that if banging on the tube under the pressure switch kicks on the well pump, it means the contact surfaces of the electrical contacts are pitted or burned, on the pump switch causing a poor connection.
So I banged on the 1/4-in tube under the pressure switch, and darn if that do the trick. Water flowing again as normal. Wife happy again !!!!
I'll check the switch contacts for pitting and burning, and clean all electrical contacts, with nail/emory file. Will contact a plumber/electrician to replace pressure switch. Switch are fairly cheap, it will be the labor that will cost.
Thanks for your responses, much appreciated !
