Question about 1999 Mazda 626
I have 98 Mazda626 And for some time have problem which is a mystery When weather is hot. Car stops.will not start for 30min Took it to mechanic hi can find anything wrong.We change main relay and starter. It was OK FOR 3-4 months 2 days ago have same problem. No one can solve this Very concern thanks Julie
Your problem is a technicians nightmare....unless diagnostics can be done when the problem happens (not a half hour later) everything will check out fine unless the computer recorded a fault...sometimes the problem is outside what the computer checks and there will be none. A single (but important) wire can either be grounding or is corroded to the point that it breaks contact at a certain temperature but not always....Therefore, every plug and connector that operates the "down" system needs to be individually checked for condition and continuity ...it takes a long time and is expensive unless the tech happens to find it early, and does not have to dig for hours to find it. Only thing I would suggest is to make sure battery connections are clean and secure and perhaps running a ground wire to both fenders, firewall, dashboard brace and engine, in addition to the original factory wiring. If the problem is with a ground, this will eliminate the problem without actually finding it.

It sounds like you may have a fuel problem, such as a partially blocked fuel filter or even sediment in your fuel tank. You advise that the car uns fine then suddenly stops, but is OK again after about 30 minutes. This would suggest fuel starvation due to blockage and the fuel is slowly seeping through the blockage and allowing you start, only for the same problem to develop again a short while later.

My old 1989 mazda had this problem as well but i traded it in before figure it out. my new but old 1999 started doing the same. it was the ignition switch. if u do buy it, buy it from an autoparts store with a life time warranty. the dealer offers ****, 10k miles or 6 mths? it has only 2 or screws,bolt? to take out and should take no more then 30 minutes to replace. pop off the steering column covers and its located where you stick the key in. its a little white and black cylinder looking plastic thing. very tiny, fits in your hand. my car would do the same work fine for months, then **** out and die and then work perfect 2 hours later. the dealer charges 200-250 for the part the auto store 100?. after installing it may act weird.. your car idoling will be off for a bit. turn it off and on for 10-20 minutes, drive it around the block if you can. turn it off again etc. until it starts to idol mormal. i think the master computer thing built in it has to reset itself since you disconnected the battery earlier and have just installed a part tht requires electrical contact. my car does that when i replaced it twice already but then resumes to normal. try this option and see if anything happens, if not return the part and get your money back.
