2013 Yamaha 300

Starlings got under the cover and built a group nest. I didn’t realize until engine began cutting off under load. I saw a piece of straw sticking out of the vent on cover. Pulled cover and found 14 dead starlings, dead babies and nesting material. I had it towed to ramp, took it to shop. They replaced the timing belt and belt tensioner and ran it in test bucket. All seemed fine but now it has begun to cut out under load again. It will restart but under load cut off. I’m taking it back to the shop. IDK if this is bird related but symptoms are same.
