No, it's not "normal" at all.
I'd guess an amperage overload, whether hydraulic or mechanical. Low voltage from the battery (or converter, if on shore power) will cause an increase in the amps needed by the pump or motor, generating heat and tripping its thermal overload circuit breaker. Those will auto-reset as they cool.
Another possibility: Many slide systems also have amp-overload protection intended to stop the slide if it bumps into something (stalls out). The amps increase as the motor strains to move the slide against resistance and the overload breaker opens to prevent motor burn-out of damage/injury because the slide has bumped into something or somebody. That sort of breaker resets almost immediately.
A weak battery will perform ok for a few seconds but then the voltage takes a nose-dive and the amps climb proportionally. That likely causes either an actual thermal overload or a false mechanical overload condition. Since it happens on all your major power consumption devices, I'd say weak battery is the most likely cause.
