6 Power Train problem

Failure Date: 01/01/2011

Since I purchased in 2009, engine kills anytime, mostly when gas pedal not pressed. Pulling out of parking lots, sitting at red lights, or letting off gas on interstate, engine just kills. Sometimes feels like a jolt. I have to put the shift in neutral and restart the engine. Records of all visits for the problem at dealership. Never could solve problem, but too unsafe to donate to my grandson. If something were to happen to him because of a defect that was never found, I don't know what I'd do. Cannot check transmission fluid level. Sealed. I do have some fluid stains on my driveway. For years I've reported to the dealership and specified the concern for safety but to no avail. It kills anytime. May not die for a week, or tomorrow, or even a month. No particular pattern. Feels like a transmission problem. If I'm sitting in a parking lot with motor running, sometimes it just kills. It's the shifting to neutral while driving on highways and streets to restart while moving I'm worried about. I've had several mechanics claim they fixed it but to no avail. Please give me some direction. All the shops I've gone to are reputable businesses. One mechanic said the electronic brain (computer box) might be causing and said to send it to Mercury for recalculation. I don't know about that. Most of the read outs are epa related.
