Hello My name is Bryan I will be glad to assist you today in answering your questions.
This sounds like the main ecm relay is dropping out, on the driver side under the hood near the windshield wipers is a black box, there our 4 bolts that hold it down in side is a relay that will fail that can cause this problem. I would check the relay and if needed swap it out for one under the dash as long as they look, identical you should be find to swap it around. Best regards,Bryan
