This stalling then starting again(30-60 min.later) problem has been ongoing with this car for a year and a half! My kids and I have been stranded in some of the worst situations due to this thing,any advice I can find would be helpful.Have had it to two different mechanics and neither one can duplicate or diagnose the problem.Fuel pump is new,starter is new,some relays were replaced,vaccuum hoses...i'm just at a loss.Please help....
