Why does a Suburban run for a little while then shuts off?

A Suburban that runs for a while and then shuts off could be experiencing several issues. Common causes include overheating due to a faulty thermostat, fuel delivery problems such as a clogged fuel filter or failing fuel pump, or electrical issues like a bad ignition coil. Additionally, a malfunctioning sensor, such as the crankshaft or camshaft position sensor, could cause the engine to stall unexpectedly. It's important to diagnose the specific issue through troubleshooting to identify the exact cause.
