Stalling on other Suburban years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2017.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the battery (4 reports).
Recalls and investigations
4 recalls on the electrical system cover the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
A component missing from the drivetrain transfer case may cause the front and/or rear wheels to lock up without warning to the driver.
In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.
In the affected vehicles, an electrical signal short may cause the transfer case to shift to neutral without the driver's input.
The subject vehicles may have a transmission oil cooler line that is not securely seated in the fitting.

Is this a known problem?
The manufacturer has sent NHTSA 16 service bulletins or notices for the 2015 Chevrolet Suburban that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

Should you keep driving it?
This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
