This is essentially your problem. My mother-in-law watches those HGTV "flip this house" types of shows. I happened to remember one episode where they were having issues with a hot tub that wouldn't work. Turns out - it was a GFCI outlet that was wired into another GFCI outlet and they'd trip each other. That little nugget stuck with me, but never meant anything.
Fast forward to reading threads here - and I've read the same thing.
It doesn't necessarily *always* trip the GFCI, it can be inconsistent.
Your only option for it to consistently work is to not plug into a GFCI outlet.
