The breaker, when tripped, has a red or yellow flag popped out sideways. Push it back in to reset it.
The reason it works when the engine is running is because the alternator output has triggered the cross-connect relay and is supplying 12+ VDC to the generator's starting circuit.
The reason it doesn't work when using the emergency start switch is because the switch gets its activating voltage from the house side of the cross-connect relay, which, of course, is dead with the breaker tripped.
This is assuming everything is wired normally - it may not be with a used coach. Find and check that DC breaker!

Ted,
I tip my hat in your general direction and I owe you a beverage or two.
Thank you for your efficient diagnosis, I found the breaker with the yellow flag out. Reset the breaker, hit the start button and genny started right up.
Thanks again,
Rick
