Why does my car stall, with oil and engine warning lights on and right after all the meters gone crazy?

My concern is about my 2008 aveo which started having the oil and engine warning lights on right after all the meters gone crazy.



As i reached a stop light, i turned-off the engine but would just krank.



After, say 10 mins. somebody helped me and got it started, and I was able to reach my destination.



Upon leaving work place, it started without the oil and engine warning lights on. Turn it off and on again, seemed to work alright until i slowed down towards a traffic light then the oil and engine warning lights turned on while the engine quitted.  It would krank but would not start the engine.  Someone helped me again using car-to-car battery jumper and got the car running.



On a normal city driving manner, the engine died again with the the warning lights on.  Then, upon installing new battery, it was alright. I parked and started 5 times to visit several mechanics and electricians, still it seemed well although the engine warning light was on.



The electrician appeared to have gone tired waiting for the codes to be displayed, as he just detached the battery and then of course the engine warning light turned off. The senior electrician tasked me to drive around and return once the problem recurs but, after successful acceleration and decelaration with a stop at another traffic light, i was still able to accelerate when the light turned green.



I could not remember if i stepped on the brake when the car just quitted again after travelling maybe 100m or so.  I could hear the alternator ticking while the oil and engine warning were on.



After about 30 mins. of trying and waiting, the engine magically started, despite the fact that it would just krank and not start earlier.



(By the way, all these happened in the same day.)



I have tried tightening the fuel cap.  And, I am told that if i just keep the head lights off, it should fine. (based from the mechanic who drove the car, as he was able to make it start with the aide of several men pushing the car)



The service center tells me to replace the Alternator, Camshaft Sensor and the engine Valve Cover Gasket. But, they further claim: should it not resolve the case, maybe the ECM might need replacement.



I haven't seen the diagnostic report nor the quotation, but i will do today.
