A Newbie with a question

Hi guys .

I'm from Saudi Arabia .

I'm new here . My father has a 1997 Mercury Mountaineer V6 with 153K miles .
The car starts fine but after 20 minutes of driving the cars starts to vibrate then it dies . When I try to start the car the engine starts with rough idle then vibrates and misfires finally it dies . I have to wait 5 minutes until the car cools down then when I start the car , it works normally . I've changed so far the fuel filter, spark plugs and wires . Help please ??

Does it die only when idling, or when you're pressing on the gas?

When the engine idles the car starts to vibrate and when I press the gas it dies right away .

Could be a bad IAC. Do a search, there are many posts on this. Also, have you pulled the codes? There may be a code stored even if the CEL is off.
