It just never ends! (sorry, kinda long)

I love my Chevy, its a 43 year old daily driver I picked up last year, for the most part it's been a damn good running truck for the year I have owned her. being all original but it seems when it rains, it pours. When it has a problem, they come in pairs!(or more)

Now the novice sunday shade tree mechanic in me is stumped.

It received a tune up last spring: Fuel pump, new distributor, plugs, plug wires, fuel filter, air filter, carb rebuild, coil, battery, oil change to high mileage blend, fuel pump.

It has ran like a top every since then, It received another tune up this spring as well: spark plugs, new heater hoses, new upper and lower radiator hoses, full cooling system flush, new thermostat, new air filter, new fuel filter, this was all TWO WEEKS AGO

So my dad makes the comment to me, "hopefully your water pump doesn't go out, Chevy's like to do that when you flush their radiators from my experiences"

Well, the old man totally jinxed me and it appears I'm getting a little weep action from the water pump now, noticed as of the other day (no biggie, water pump is no big deal to replace)

The problem now is for whatever reason, my engine keeps shutting off unless i give it gas, accelerating or slowing down in gear(its a manual). When I push in the clutch, if i'm not giving it gas, the idle drops really slow, then it dies.. Thoughts?

Thanks for the help! You guys are awesome
