Will not stay running

However, if it stalls as soon as you put it in gear or even start to let the clutch out, then I suspect the clutch is failing and not fully disengaging? So when you put it in gear it pulls the engine down and stalls it. Does it jump a little or jerk at all as it is stalling or does it stall out like it is running out of fuel?
