Disconnect all zone wires and see if timer blows fuses. If not, one of the zone valves is drawing too much amperage.

    If your sprinkler timer indicates which zone or station is shorting, only disconnect that zone wire. If the timer works properly after that, there is a problem in the disconnected zone wiring.

When on auto mode, the system just keeps repeating the zones.

I don't feel you can repair system by yourself. Excuse me if you can; so do it.
You should take it to an authorized Rain Bird repair service. Look for it on some listing they might have given you when you bought your stuff or contact them from here:

System quit watering. Tried man/adv and won't energize sprinkler valves. I can operate sprinkler valves manually. Tried unplugging power source to reset. Any suggestions?

Most sprinkler valves run on electricity from the timer. If the time doesn't send electricity out, the valves don't open. If an animal has chewed through a wire, that valve won't open.
You can take a meter and check the voltage on the wire at the timer. If nothing, replace timer.
If you get correct voltage at timer, measure at valve. if voltage good there, replace valve.

Can i put two valves on one station

You should be able to put two valves on one station. If it is too much for the timer either a fuse or a "virtual fuse" on the circuit will fail. Just turn the unit OFF, separate the two valves and turn unit back ON to reset "virtual fuse".
I am an irrigation contractor and we have many timers with doubled zones.
