So you have a loose connection that is connected until it warms up. Have you got pigtails in the boxes or are all the wires just stabbed into the back of the outlets?

While you were in there did you torque the other whites? If one is loose others could be.

^ Yes sir, " I did just that and tighten ALL my neutrals. To my surpise a few needed tightning."

^ " I replaced all the wall plates when I first bought the home and I do have the screw down connections and NOT the push-lock style." So, all my outlets and switches are the hook/pig tail, screw down type.

The problem was at my breaker panel itself in the garage. On each side of the inside of my panel there are neutral/grounding block terminal strips for all my homes circuits. (insert wire in the terminal block then screw down fastner) The neutral wire from that particular circuit was loose in that block causing the failure in that circuit.

High contact resistance connection due to low contact pressure. Five watts may not be enough to heat up the neutral busbar at your connection but you could have had 10x this much power, up to maybe 300w.

This is an excellent practice ... Don't have to kill it by over-tightening, but firm retightening is a great preventative. Nicely done!

You are very luck to have found the problem in the loadcenter . Many time , you have to spend a lot of time and effort searching for the defect . :-(

Since you do not usually know the rout the Romex takes from the loadcenter , to device , to device , to device .....

As I think someone stated , it is often in the last non-dead receptacle . Another problem , a home owner often forgets where all the receptacles are . And it ends up being behind the heaviest piece of furniture in the house . :-(

More often than not , it is in a receptacle , than in a switch box or lighting box . Since receptacles often carry heavier current loads .

Good job !

God bless

The current in a series circuit, i.e.,
-receptacle-switch-breaker-
is the same.

Still, these may fail at a higher rate for other reasons, probably mechanical wear.

BTW, IMHO, I think God damns more than He or She blesses.
