98 Eclipse Spyder GST automatic
I've been battling issues with my car for a while now. First was what I thought was overheating turned out the gauge sensor was climbing with temp not being very high. However, another thing that has been going on intermittently for a while is my car dying when I've been driving for a while. I can drive to/from work (~10mi each way) without issue, car drives fine. However, if I start running some errands or drive across town, where I'm driving more than about 15-20mi within a short time, I'll have episodes where the car will suddenly stall out, die and I have to pull off the road. It will turn over, but no start. Now, if I sit there for 15-20 minutes, it will start back up and I can drive again, however it will be more likely to do the same thing in only a few miles until I let the car cool off entirely.
Now, I've done a number of tests. For one, last year, I thought it was coils or power transistor and replaced them. Didn't run into many issues (right before winter) then weather starting warming up and I've run into the issue again. I've replaced them again with used parts, but still issue occurs. I've tested CAS, which all tests are within spec. Same with the CPS. When I unplug the CPS, it produces the same symptoms, however I specifically idled the car today for a while hoping to reproduce it (without being stuck on the side of a road) and it actually did it when I turned off the car and went to restart, however the CPS was still producing the proper voltage when I was cranking the engine.
Coolant sensor and temp gauge sender are both new. Coils and PTU are new/used. Wires were just replaced <10k ago (since having this issue prev). Plugs are new. No issue with fuel as the rail is pressured and occasionally I'll get a sputter when trying to start during the issue occuring. Charging system working fine. I unplugged the capacitor and car ran fine without. Unplugged the CAS and it will start and die after a few sec (not similar to my issue). My car has the black case ECU, which I just opened up today and it looks fine (only one electrolytic cap, which looks fine, no burnt components/traces). I have a spare, which I just put in and am going to test here soon, but I'm not very confident that is the issue.
What else am I missing? What else could it be? The car runs great except when this issue arises.
