Could be lots of things.

Low fuel
Fouled plugs
Running lean (multitude of different reasons)
Wrong ignition timing
ect ect

When does it do it exactly? Particular gear? Particular load? After climbing a hill?

Doesn't matter what gear cause when it gets 5000
rpm in every gear it starts to miss it does not after a hill climb

Had the same problem in my first et. I found out it was the cheap crappy ignition leads I had on there. Swaped them out for 10.0mm ones and problem solved.

Worth a look. Other things to consider is ur electrical wires to the coil and ecu plugs.
