Generator runs sometimes and then shuts off.
Replaced with new:
Spark plugs, oil change, oil filter, air filter. "still no run"
Replaced:
New carburetor, New fuel pump, New fuel filter, No gas line hose from carburetor to fuel pump.
"still no luck"
The in line 10 amp fuse above stop/start switch is okay. The 20 amp
two blade fuse by breakers is okay.
I help "stop button" in for 15 seconds to prime Gen. and then hit start button and it started and ran for 60-90 seconds and then started getting rough and shut off and would not start.
I ordered new 5 blade relay plug under air intake to see if that is problem.
Are there any other in line fuses that could be problem
Any suggestions would be greatly appreciated.

You need to make some friends at a local small engine shop. Onan engines are all over the place and they will probably have seen this before.

Stop throwing money at it!
Have you checked for spark at the spark plugs?
Possible bad coil or plug wires.
Does it make any attempt to fire? Any back firing?

dalefuji,
Did you replace the gas line from the fuel pump to the gas tank?
If it ran when you primed it, you filled the float bowl with fuel and that allowed the generator to run for a short while. But with a leak in the line between the fuel pump and the gas tank, fuel can't be sucked up fast enough and the engine will stall.
One way to check is to take a line from the fuel pump into a separate gas container and see if the engine will keep running then.
Good Luck,

^^^^This is what I would be looking at. An issues somewhere with the fuel line running from tank to generator. If it's sucking air along with the fuel it won't run for long.

I took fuel line from fuel pump and stuck it in gas can and no luck still doesn't run.
I checked old carburetor and it seems clean and okay. I think the new carb. is stuck and not working properly.
