Is there a combination compressor/generator powered by gas or diesel?

Yes / no. The only one I know of commercially is the Miller Air-Pack
which is a diesel welder/generator/compressor. You could however
assemble one quite easily. Get one of the Onan 6.5 KW commercial RV
style generators that has the extended shaft typically used to power a
hydraulic pump for a lift truck and then couple an inexpensive
compressor head to the generator and use an electric clutch or air
unloader valve to control tank pressure.
