Onan 7000 keeps blowing side 10mp blade fuse

Onan 7NHMFA261050, 1994 or 95 year in Allegro Bay by Tiffin. Been running fine, sitting still ready to leave next day just shut off wouldn't restart. Found blown 10amp blade fuse on side, replaced, started and ran maybe 30 seconds blown again I checked wires around and behind choke to relay. Replaced relay behind choke, still blows fuse, unhooked choke wire, new fuse restart runs maybe 30-45 seconds blows fuse. Electric fuel pump pushing good stream when I unhooked at filter by carburetor and turned over with new fuse. I checked 10amp glass fuse in circuit panel board and removed board, no burnt places or swollen parts, put back in place. I know fuel solenoid getting power since it's power comes right of electric fuel pump hookup. I read where someone asked if it blew fuse as soon as replaced on some model but this needs to running for fuse to blow. The pump is in such a location I would like to know before I attempt to take it out if it's the problem. Anyone know where I might get a wiring diagram that shows where those wires go to from relay? This setup has no room to hardly reach anything. Any help or suggestions would be greatly appreciated.

That glass 10 amp fuse is usually for the remote start/stop switch. Check the remote start/stop switches for issues.
