My first go to would be to clean the air filter. I had a 400four which would run well for a bit and then would not rev hardly at all and got increasingly worse. it turned out to be a damp sponge at the entrance to the air filter box.
Sounds like a carb problem do you use a choke to start it, does the choke fully disengage when its warmed up? I remember the old manual choke levers and sometimes I would forget to turn it off until the engine started stalling.
I had a 3TA years ago that did a similar thing. It was down to a worn carburettor, weakening the mixture.

I believe it is .was also thinking of removing the choke altogether and just use the tickler on the carburetor
I believe an Amal 376 is for a 500 yours being a 350 probably should have a 375.
