i have a random stall after long road trips about 238 miles car runs good dosent stall on road . when i get to my destination i unload the car and it sits for a half hour i get in it starts no problem go to a store and when i come out and start the car it stumbles and stalls it did this twice. it fires after that but some times i have to push on the accelerator pedal to get it running .but it dosent do it all the time . im getting fuel pump pressure checked o tuesday

could be a number of things....dirty throttle body/plate....dirty IAC pintle...bad IAC or harness/wire connection....leaking fuel pressure regulator.....bad MAF or dirty sensor, etc....

Scanned for codes?

My '01 Le Sabre had the same symptoms. Replacing the 6/3 coil fixed it.

You may be lucky and need only one coil.
