How about a good ol fashion tuneup--inspec plug wires and dist cap-bet theyre worn--ignition module may be failin--dont forget about a worn gas pump or pressur regulator
There are a few things that can cause that to happen, a faulty fuel pump or fuel pump relay, a faulty ignition module or pick-up coil/stator inside of the distributor, a faulty ignition coil, or the ECM/ECC (Engine Control Module)/(Engine Control Computer) it will be called one of the two.
The ignition module located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil. A faulty ignition module can cause any one of these systems to malfunction.
That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores.
If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.
To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged. Let me know if you require any further assisance.
Pull the distributor and check the drive gear. if it's worn at all replace it. you can replace the gear or the distributor. if you need directions let me know
You might want to check fuel pressure at the fuel rail as your pump or regulator may be going
