Hi Jim, up until several months ago I had a similar perplexing problem with an outlet in our kitchen (go figure). The silly thing would occasionally quit, I'd automatically just replace the outlet, things would work for awhile, then it'd happen again. I finally got tired of this scenario and decided to check "ALL" the outlets in the kitchen. As it turned out (in my case), another outlet (upstream) had loose wiring which occasionally worked loose, and hence caused the downstream outlet to not function. Nothing was ever plugged into the problem outlet, so I never suspected it. Bottom line, check "ALL" the outlets that may be on the same circuit to insure that they are in good condition.
