maybe new house is the problem and you got some shitty electrical work done.Just shitty luck I'm assuming. Both were always used within the depth markers. When the 2nd died last weekend it had been running for an hour and a half. New house since last use so probably not electrical.
maybe just get one of these
Bastex Socket Tester with GFCI check. Receptacle Tester for Standard AC Outlets. Includes 7 Visual Indications and Wiring Legend. Automatic Electric Circuit Polarity Voltage Detector Breaker Finder
i saw my house inspector use it on every outlet, actually found 2 fault gfci outlets, it was promptly one of my first house purchases too. (even tho i know zero electrical and the inspector already did all the checks, i just have it around and use it when i was sorting out where my breakout box lines where going to)
