1996 Mazda 323

Hi, I start my car and drive it out of my drive way and its ok, but after 20-30 seconds it loses power, I put the trottle to the floor and still it doesnt pick up, even in 1st gear, theres no water in the oil and no oil in the water, as I drive the car is splutering, or chucking, I would really appreciate any feedback you could give me, Thanks.
