I have three of Mitsubishi generators and on two of them they did the exact same thing.
I had to take the generator off the engine and found that one of the wires on the case windings had burnt off.
I soldered it back on and solved the issue.
to be honest I find this with a lot of these Mitsubishi generators they cannot handle the long term load hence why I have three and people throw them out rather than repair them

You can contact the supplier who provide the Mitsubishi generator for you, they can help for you.
If you still want to have another generator, suggest you have Cummins diesel generator, because Cummins is more popular all over the word, and it is easy to maintain.

Here is a manual for a newer mge model. I don't think your going to find a manual on the older mgb around and they tend to be very similar from one model to another so it should help. Though you should be able to get parts.

As for the gfci brand, I have not had any problems with any of the brands out there. So the cheapest is the best. The 30amp socket could be 110 or 220vac. If there is a selector switch on your machine. If not, there should be a NEMA number on the face of the socket (ie 15-5R). The R stands for receptical while a P stands for plug.

Here is a plug configuratio diagram that will help identify your plug and the voltage it puts out. These are standard so you can be sure that if it the same plug it will put out the same power. Be carefull to ensure which side is larger or has a tab is correct.

While replacing the plug just swap wire for wire in the same place as your new plug. Gold connector to gold and silver to silver.

The inside of a small generator is very similar and if this don't help I can walk you through any connections you have questions on. Pictures would help if it comes to this.

here is a wiring diagram for that engine:
