Runs great for a week or more; then bouts of stalling less than a mile from house. Fuel pump is ok. What part of ECM system would be so temperamental and have enough power to blow fuses. If I let it sit; odds are I can drive it 100 miles or more before it starts blowing fuses again.

    Thanks! Think I've narrowed it down to a bad fuel injector. Would that cause the ECM fuse to keep blowing and intermittent stalling
