T25 2.2 D4D Random stall

[Jokerz]

Hello guys.
I have been experiencing a very odd behaviour of my Toyota recently. 
It randomly stalls. No lights, no nothing, just stalls. Doesnt happen at idlle, happens even on large speeds like 60mph , or 20mph and i cant seem to find the cause. When it dies sometimes theres the "wrench" symbol for a few second , then it disapears and theres no power. If i stop, turn the key off, then try to start, nothing happens - it cranks but does not start. After removing the key, locking and unlocking the car i can start it again. Checked the car with a OBD multiscanner but theres no fault codes. 
Help?

Spanner symbol means that a service is due. When was your fuel filter last changed?
