2000 Mercury Sable Wagon GS 3.0L Vulcan engine. 182,000.00 miles. Starting today I turned the vehicle off at my garage. When trying to restart engine it would turn over again once but would not start. After letting engine sit for about an hour it started. After turning vehicle off tried to check for any set codes but scanner showed no link to computer again vehicle would not start will try again tonight after engine cools off. Any idea what is causing this problem? I know electrical problems can get pricey to fix, hopefully one of you guys have had a similiar experience and can pass along the fix. To me problem sounds like something has become heat sensitive. Is engine computer going bad, is there a wiring problem? Just bought the car and if it costs me a couple thousand to fix this would really suck. Bob S.
