Silly question, but have you checked your fuses? (EFI and fuel pump) as well as engine/ECU fuse.. also swap your EFI and fuel pump relays with headlight/horn relays (as long as same type)..

So you did swap EFI and fuel pump relays with horn/headlight relays? (just to elliminate a faulty relay) and you checked all fuses?

Also, did you turn engine off before you went to drive again or was it running continuously and then it just cut out as you went to drive away?

Did you check negative link on the engine-chassis connection as well as battery to chassis cable connection.. not loose?

Is the engine turning over nomally by the starter motor?

Have you got an aftermarket immobiliser or alarm fitted in the car?
