Today while i was on the move to job suddenly i felt little vibrations comming from the engine! I looked at the board and i saw an orange light (it was the engines light!)

I Stopped the car and turned it off. A Couple of minutes later i turned on ignition and it turned off! A few minutes later i turned it on and i felt again little vibrations from the engine the engine had a weird smell, like overheated catalyst

I left the car that place an in the noon i will take it to garage.
Does anyone knows what might this be????
(Sorry for my English..)
