Frigidaire FRS26ZRG tripping gfci outlet

My Frigidaire FRS26ZRG will still run, for a few hours. It will eventually trip the GFCI outlet that it is connected to; thus losing power and shutting off. I have tried connected it to multiple outlets, on different circuits with the same results.

Anyone have ideas of where I should begin to troubleshoot what is wrong with it?

Thanks,
Matthew
