Engine cutting out at WOT

[JC2005]

My new Predator 212 engine will not keep going at wot or even 3/4 throttle. I broke it in, then replaced the oil. It only has about 4 total hours on it. At first, after break in, it ran full blast.
I am running fresh gas in it and have checked the oil level. The fuel tank was 1/4 full and I thought that the velocity was sloshing the gas around too much so it is now about 3/4 full and it is still cutting out.
What's weird is it will run strong at wot to the top end, then it starts cutting out for 2-3 second intervals before it picks up. It's almost like a temporary vapor lock, but the tank is vented.

Any ideas?

Thanks

I'm almost sure you already checked, but just to rule it out:

Please check the low oil sensor cables not shorting out.

I would also think it might be the low oil sensor

I had to exchange out this engine. A bolt connecting the body of the engine sheared off leaving some of the bolt in the hole.
Now I am back to breaking in a new engine. I'll have to see if this one has the same issue.

How the heck did that happen??

You'd have to ask the 8-year-old Chinese kid that assembled it.

well my fat as s fingers can't get in all those tight spaces! I would love to get my hands on the tool they use to set the snap ring on the governor post, my snap ring pliers can't quite get to it

Probably got something to do with the fact that I don't think it is installed with snap ring pliers, and not intended to come off. A good yank on the gear usually unseats the ring.
