It sounds like a problem with a vacuum line, but it could also be electronic. Check if there are any lose or broken vacuum lines.

Have someone check the fuel pressure to the system. If it is low, fuel tank filter plugged, pressure regulator bad, etc. all can cause that type of problem.
If there is a check engine light you need to have somebody with a OBD-2 code reader check the problem.

That engine was bad about the ignition coil housing shorting out at times.
That's just a guess based on your description of the problem.

possible coil or coil shell, need to know when it bucks ? if it s after you run it on the highway and it bucks when you come to a stop then it dies it sounds like it might be a faulty tcc solinoid. really need more info with this problem. does it buck when you are driving at a constant speed?really need more info when it messes up.

if it is the quad four engine the coil packs under the cover could be weak or faulty also check they also are known for electrical shorts one little hard to find wire could be causing all of your problems

this could possibly be the cat. converter causing a restricted exhaust system which would give you the symptoms that you are describing. i would have them check the exhaust for a restriction (plugged cat.)
