Experiencing a confusing stalling issue. Looking for help diagnosing/fixing. Basically, when I start up the car, it turns over and starts fine. It then idles for between 2 and 4 minutes, then quits. Won't immediately re-start. Has to cool down for 1 to 3 minutes, and then re-starts normally. The process then repeats (starts fine, runs 2-4 minutes, stalls). Doesn't matter if the engine is warm, or if the car is moving. This leads me to think it's an ignition issue. Could it be the DME quitting on me? Other than this, the car runs fine (when it did run). Here are details on potential hardware issues:
Any help is appreciated.
