I usually onely drive locally but the last few times i have driven the car for more than 3 hours going store to store with the wife i completely loose steering on both directions. If i raised the idle i get some steering but very little if i shut the car off for a few min. And restart I get steering back some what i do have headers i was thining it was heating up the line but it happened on a cold day my fluid looks good and not boiling over and at the right level i also have Bonneville wheels and tires 235/55r17 i am thinking its the magnasteer system i am trying to get it on the lift this weekend and take a look have any of you come across this problem thanks
