It is best to use an OBDII scan tool and scan for codes to get a detailed report on the engine.

Many modern cars have a system that will allow the vehicle to drive a short while instead of completely breaking down.

Basically, a malfunction has happened, and the vehicle has gone into Limp Mode so you can find a safe place to pull over.
