I see issues with batteries often. Which brand are you using? Have you tested other brands to be sure it's not due to the battery?
Some batteries aren't designed for high-drain devices, so when you start to strum and the voltage starts to rise, they'll cut off.
If it's a Carbon Zinc battery, it will not be able to carry a heavy load for a long period of time and you'll have this issue.
These issues are almost always a simple fix. Reach out to me through a support ticket and I'll reach out to help you with it.
