Great information, thanks. Do you possibly know what's wrong?
First thing I’d do is get a voltmeter and measure the battery voltage. Then I’d connect the battery to a resistance load of some kind, either a DC motor or a heating element or series of 12v lamps, through the voltmeter (set to amp draw setting) and measure the output amps of the battery.
If the battery checks out, use the voltmeter (on amps) to measure the current through the lawnmower.
If that’s within specs (Google Ryobi mower current specs) , then I’d check the temp of the motor. I suspect there’s probably some kind of circuit breaker that trips from excessive resistance in the positive wire to the motor. It runs long enough for the resistance to heat up the breaker enough to trip, and then it cools off and resets itself.
So break out the voltmeter and start troubleshooting.
