How to keep sprockets from jumping

[Rasure]

I have been working on a project that requires a chain and sprocket.
I have a #40 chain with 2 matching sprockets. My problem is that the chain
seems to jump sprocket under load. I am not sure if i need to get a larger
chain and sprocket or get a double chain to fix the problem. This is not an
engineering problem per say however no other forums have given me viable
solutions. Essentially there seems to be to much torque and the weak spot is
where the chain transfers power from one sprocket to the other. Any ideas?
