engine light

[djstokey]

i was driving today, whrn the engine light came on and the engine stopped, it would not start at first, but when it did, it seemed to back pop through the engine, i left it for a bit and then it started, but after a few minutes it did it again, can anyone help please.

Bit more info would be great, engine size/code, for example. Check the electrics under the bonnet, make sure nothing's loose or disconnected, an engine warning light usually represents an electronic fault with a sensor or emissions system.
Crank sensor maybe?

Usually a blocked breather on the inlet / icv system or a faulty cam sensor.
