Buy a haynes/chiltons manual, it has many troubleshooting items that you can check.

my 4.3 did the same thing.. i got a manual so i kept it revved and kept it running.. i replaced the Throttle Possition Sensor and it helped somewhat.. since then ive replaced the injectors, air cleaner, fuel pressure regulator and fuel filter... if i were you id start with the fuel filter and check ur air filter.. those r the easiest.. if not fuel pressure regulator might be clogged or your injectors (which are $120 a pop) and theres two of them... if u have a haynes manual look in it and it can tell you how to check all these
