Sounds like the Hall Sender breaking down inside the dizzy.

thank you for the response , What is the hall sender ? with replacing the engine the distributor Was hit and broken , so we have put another one on it , maybe the problem is here ? and what would be the reason he only have it when the engine is hot ?

The hall sender sits below the rotor arm in the dizzy (black plastic plug) and determines when to fire the spark. As they get old they break down under heat causing the issue you are seeing
the tell tale sign is if the rev counter is bouncing randomly when it starts misfiring
you sometimes can replace the hall sender (all depends if you can dismantle the dizzy) but its usually easier just to replace the whole distributor

And is it possible to test this ? beceaus , we have tried everything and bought allot new stuff and its getting really expensive.

Halfway down this link gives details on how to test it, its the same details as in the haynes manual.

but if the rev counter is bouncing in a random way when its happening then its definitly the hall sender
can you not get a lend of another dizzy to try?
