Car has around 160k original miles. Emission components removed. Starts every time and will idle for over an hour. Problem comes when you drive it. While cruising ignition shuts off no spark at all. If I punch the clutch in and try to restart it only turns over. It will restart if I push in the clutch, cycle the ignition switch off and then restart. Car will continue down the road and may or may not shut down again. I’m chasing down A ghost and have changed everything but TPS and MAP. Reman distributor swapped too. Checked wiring and all was good. Pulled ECM and opened it and saw the capacitors were bad so I sent it to “The EFI Guy” who replaced them for me $50.00 he did a great fast job. Car still shut off after driving for 5 minutes. Any help would be great. Timing is set at 10degrees and when the spout is put back in it does change the timing so it’s working. Ran codes and I get an 18 (Spout) Would the relay for the ECM cause this issue?
