I have a 2007 Tundra with the 5.7L V8 that exhibits a HOT restart problem when air temperatures rise above 88 or so. The Dealer (Heyward Allen in Athens) swore that it was the fuel pump & a bad key chip, both were replaced at a cost of $900.00. This did not fix the problem, they can't duplicate the issue and there are never any codes.
What could be the problem?
