Kubota rattle

Hello Forum! Our first post here, and it is a tough problem!

We recently purchased a "rebuilt" Kubota EB300 diesel generator. It ran great for a while, but has been developing a "rattle".

When it happens, it quickly looses power, and rpm drops right down. It has been happening much more often lately. The noise sounds a lot like a hydraulic lifter rattle on a car, but of course this engine does not have those!

The boat is in Thailand, and the seller is in Australia ignoring my emails

Some things we checked:
Oil pressure great
Coolant temp normal
Load is within normal range
Very little or no smoke
Injector cleaned and reinstalled
fuel filter clean
The oil looked ok when changed, no metal particles

Any possible cause? We dread it may be something internal about to really go bad!

Thanks
Jerry
