2005 Mercury Mariner. Sudden stalling of engine at speeds up to 40mph and loss of power (then recovers) at higher speeds. Notified Ford and scheduled for service twice - dealer unable to replicate and Ford response is that "every consideration has been given to the matter....unable to further review concern" we have yet another service call scheduled with another dealer because problem persists and could lead to serious accident in traffic. Problem manifested itself in July 2008 and no regular consistent pattern to it but happening more often and stalls happening more often. Afraid to drive vehicle in heavy northern va traffic due to its unpredictable stalling and/or loss of power. Reporting in case to be on record, in case other complaints filed about this issue with this model, and for future reference in the event Ford unable or unwilling to fix a serious safety issue.
