Coach power problems

No when I'm saying the power comes back on it is coming from the generator. I can see it on my remote display. It shows I'm drawing about 8 amps with both roof air units off.. As soon as you kick the roof airs on and they start to draw a big load it kills all power from the geni.. The airs kick off, then a couple seconds later the power comes back to the coach (from the geni) Airs try to start again, power shuts off.. And it just keeps cycling like that.. Then generator will idle up as soon as it senses the pull from the AC's but then the power is killed and it idles back down.. If left alone this cycle will happen about every 15-20 seconds.. Turn both airs off and power comes back to the coach from the geni. Its almost like your flipping the transfer switch on and off if that makes sense. Bill I've not tried it with just one air yet.. It is an Onan 7500 diesel. I was thinking this morning that maybe both compressors tried to hit at the same time and it sent it into some shut down mode and was sheading power..
