It sounds like low fuel pressure could be a real possibility. It could be a partially blocked filter, weak fuel pump or a faulty fuel pressure regulator.
You may have some bare wires that are shorting out on the clutch pedal. Get under the dash and check it out.
The question is vague but I know a Mass Airflow Sensor issue causes the car to stall out when the gas pedal is applied like it has no power when in gear. The car may idle okay, I've even seen my friend pump the gas while it's in gear and gets the car moving but while the pedal is held down and the clutch is out the car will die.

Your timing is off.
There are several things that can cause your truck to stall. The most common causes are a lack of fuel or a lack of air. Check your fuel filter and your air filter.
check your O2 sensors.. my 2300 did it when i first got it and all i did was clean out the top O2 sensor with some carborator cleaner and it ran fine after.
sounds like your distributer is getting moisture in it
ANY car will stall on a proper hill if you try to bring the clutch up without any revs generated from the gas pedal.
Try checking out your catalytic converter. it may be plugged which causes you engine to die after you drive it for a bit. try checking your gas for water that may be the problem also chek your fuel filter it may be plugged.
youre lifting the clutch up to quick
A 1998 Honda Accord could stall because it is out of gas. The car could also stall because of a bad computer.
Could be as simple as needing a tuneup with a new set of spark plugs.
