1993 Concorde Will Not Restart Sometimes When The Engine Is Hot

I Have 1993 Concorde With A 3.5l Engine. When The Engine Is Shut Down Hot, The Engine Will Not Restart For 20 To 30 Minutes. This Does Not Happen Very Time The Engine Is Shut Down. I Have Ruled Out The Fuel Pump Because The Car Can Set For 2 Weeks Without Starting And Fire Right Up. Therefore, I Feel The System Is Holding Pressure. Has Anyone Experienced This Problem? One Dealer Thinks It Is The Fuel Pump!

Check your air filter. If it's dirty or clogged, it'll cause that same problem.
