Vehicle Shudder problems of the 2012 Volkswagen Golf

I was driving down the road had just shifted into 4th gear came up to a red light. I pressing in the clutch and started to slow down still in 4th gear. The red light turned green before I could slow down much at all. I released the clutch when I did this the engine and rpm increased. I was still in 4th gear and hardly accelerating but it felt as though I was in second gear. I kinda freaked and looked to make sure I was in 4th and I was. The car began to run normal so I just brushed it off. I came to another red light and made a complete stop. This is when the car began to shake and flash the orange coil looking light. It completely shut off and I was unable to restart the car. My brother came and helped me push it to the side of the road. It had to be towed to the dealership.
