2000 Mercury Marquis • 80,000 miles

My 2000 grand marquis has an occurring problem. At speratic times, the car runs rough and then wont start. This will happen every now and then and the only remedy has been to let it sit for a long period of time and then I start it up and it runs great. This will happen every 2 or 3 weeks. No rhyme or reason. Please help me.

This can be hard to nail down only ha pining once in a wile. When its not starting you will need to make some checks. Fuel psi and spark. The only other way is to through parts @ it. I dond advise that.
