2008 Daewoo Damas Daewoo Racer GTI 94

The car engine seems to have a power failure problem, it suddenly decreases its speed while I was accelerating and it seems there no more gas eventhough it has plenty of fuel, it also seems the fuel supply is not enouigh for the engine, likewise it maybe that the electronic supply is failing. Please help me with this.
