My problem started only a couple days ago. When I start the car sometimes it just dies and I have to restart it. Also, while I am driving it has a prolonged shift and makes the car "stutter". I think it is a spark plug problem or distributor problem. But, I am no mechanic. Any ideas as to why this started?

Any recent work done on it, and did it start after a refueling? Is the service engine light on? If so get the codes read, Autozone reads em free of charge, then post results here.

Yes I have done some work on it recently. I replaced both of the cv joints, or elbow joints. I also replaced the belt. So the distributor did have to be removed in order to make the repairs. No, the check engine light is not on, and I did refuel recently but it was a full tank and it started at the qtr tank mark.

Possible Cause & Correction Check the following items: Check ignition wires for short or faulty insulation. Check distributor cap (if equipped) for moisture, dust or cracks. Spray spark plug wires with a fine mist of water to check for shorts. Using Spark Tester (J-26792), check for available secondary voltage. Check ignition system for faulty grounds. Ensure ignition control wiring harness is not routed too close to wiring which may cause induced voltage signals. Check ignition coil connections. Remove spark plugs and check for correct heat range, wear, cracks, wetness, improper gap or heavy deposits. Check for poor quality or water contaminated fuel. Check for improper fuel pressure. Check for restricted fuel filter. Check for plugged injectors. Perform injector balance test. See appropriate SYSTEM & COMPONENT TESTING article. Check PCM for proper ground circuits. Check for internal PCM intermittents. Check for bent push rods, broken valve springs or worn camshaft lobes. Check for sticking EGR valve. Check TP sensor for sticking and binding. Check for correct TP sensor voltage. See FUEL SYSTEM in appropriate SERVICE & ADJUSTMENT SPECIFICATIONS article. Check for proper crankshaft position sensor resistance. Check for restricted exhaust system. Check injector drivers by disconnecting all injector harness connectors and connecting an injector test light (noid light) to each injector's harness terminal. Light should flash while cranking. Check engine compression. Check for incorrect valve timing. Check intake and exhaust manifold passages for casting flash. Check distributor vent system (if equipped). Is yours 3.1, 3.4, or 3.8?
Also check voltage at all fuses marked IGN like IGN1 IGN2 etc, should show battery voltage, if it's low, check wiring, If wiring is good this would be due to a faulty ignition switch, and can cause your concern!
