Kohler Generator Mechanic Recommendation? Rock Hall

I am looking for a recommendation on a good Kohler generator repair technician / shop in mid - upper bay area (boat is currently in Rock Hall but will be in Middle River in the spring).

It is a 7.3 ecd that starts but shuts down after 20 minutes or so with the UU code.

Any recommendations? Trying to avoid pulling the genny and shipping it down to Florida for a rebuild (current marina's mechanic recommendation).

Thanks,
Matt

I ended up having to pull my generator and taking it to a guy in Jacksonville to get it fixed, after my maina's generator guy could not get it working. It sucked, but now I have a working generator.

If you're in Rock Hall, Haven Harbor can fix anything. Pretty sure they are Kohler certified.

Thanks, but that is where the boat is now and they have already tried to fix it. They recommended pulling it and shipping to FL....
