Go out during the ride

So I have the following problem with my Gilera SMT 50! So I drive quite normally with say ma times 7000 umin all of a sudden she goes out so as while the sprit everyone! poob poooob poooooooooooooob off!!!! spits is aba enough indoors! if I kick right then she doesn’t even run along with me and also not with chuke!!? well but I found out that if I just let her stand for 2 minutes and don’t do anything I just need to kick once and she runs again, but then again only 3km far!!! I have already cleaned the candle! I cleaned the carburettor and I am honestly at a loss what it can be!! although I have a presumption! with me was so that I had forgotten my tank stubble on a filling station! but with me is jo so ne cover and was u then about 1 hour standing in the rain and hail! so can it be that was in the tank and that then leads to it going out?? well so far CHE
