Most vehicles that run EFI will run like crap when you run it out of gas. The fuel pump will go south as the fuel is what keeps it from burning up. If you run your vehicle out of gas or near the fumes state the pump will eventually burn up and stop working. It sounds like you burnt the pump and after it stopped working the sled ran out of fuel on the one cylinder and the other side still had some to run on and with no lube it's too hot and burnt the hole. Don't know much about the sleds as it's too warm here in So-Cal but it's what makes sense as all EFI's need an electric fuel pump either in the tank or in the fuel line somewhere near the tank. After checking the engine and replacing parts I would also replace or check to make sure fuel pump is not burnt up.
