2001 Hyundai Accent

When i change gears from first to second, and from there to third and then to ourth gear, the car stalls. Once i have 4th gear the car runs fine and it does not give me any problems to change it to fifth. Does anybody know what maybe the cause, remember once i get up to the 4th gear the car does not stall. Can it be the clutch? I’d appreciate your input. Thanks in advance
