Engine keep going off while in motion

Maybe someone had posted this before, but I am desperately in need for a solution to this problem. I have Chevrolet Lacetti 1.6 2004 model.

The engine keeps going off while in motion. This has happened several times and I took the car to two Chevrolet service centres. They checked and said that they could not find out what is wrong with the car.

I changed the battery thinking it might be the cause but the problem continues. Another mechanic suggested that it might be bad fuel, I changed the fuel station to BP. Yesterday it happened again while I was on the motorway. It went off once, I started it and it drove for 60 miles without going off again.

Well we would suggest that all air/vacuum pipes are checked, then all fuel pipes/filters are also checked.
If all okay then we would suggest that the following are checked.
1. CKP (crankshaft position sensor)
2. TP (throttle position sensor)
3. IAC (idle air control valve).
Regards
