Hi all! Annoying issue below regarding a 94' Grand Cherokee Laredo 4.0L 6cyl.

Last week the truck was idling and stalled for the first time. A week later the engine failed to turn over; I was receiving power from the battery but no spark from the ign. coil. I was able to get it started to drive home by resetting the computer. On the way home, the truck stalled at a red light but immediately started when I turned the key. I replaced the ignition coil, fuel filter, distributor cap, rotor, and checked my connections, fuses, and the spark plugs are new plat. tips. The engine continues to stall while idling and driving. Sometimes the engine stalls immediately (cold) or after it's been running for some time (hot). The engine only turns over intermittently (most of the time but occasionally will not start again after it has stalled). Does anyone know what could possibly be the issue and where is the best place to start? It is also notable that there is no apparent vacuum leak or fuel leak. Thank you all in advanced, this is driving me crazy!
