I have not had the problem fixed yet. A mechanic suspects a clogged gas tank filter. Problem is, it looks like the entire gas tank has to be removed to get to it, and it is not a sure bet that that fixes it.

I have a 2002 Santa Fe (6 cyl) with only about 35,000 miles on it and this identical problem just started for me about six months ago. Maybe it is a fuel filter. I have to admit I do run the fuel level down too far (same money used to keep it a lot fuller!) Anyway, does anybody else notice a correlation between the problem and letting the tank get low? I'm not sure if the two are connected, and I'm still not sure why if it is the fuel filter, why does it clear up? I know that many cars these days have pressurized fuel tanks. I wonder if the problem may have something to do with taking the cap off and depressurizing the tank... I say this because I can shut the car off a few miles later, wait a few minutes and it starts right back up. The only difference I can see is that I didn't remove the fuel cap. Any ideas on this?

I do not think it is a pressure problem. If I only put $5 of gas in to a fairly empty tank, the car starts as normal. If I fill up past 1/2 tank, the problem happens. It seems like air or vapor must somehow be trapped in to the fuel line.

Sounds like the emissions evaporation system could be clogged? Charchol cannister might be soaked or otherwise bad? I am reaching here, but it might be worth a shot.
Also it's possible you have a bad gas cap that is not properly venting. Are you putting it on tightly enough to click it at least three times after fill up.

Not a bad idea. Let's see... if it were the emissions evaporation system, why do we only get the problem at gas stations when restarting? ALL my other restarts are perfectly normal, including first thing in the morning, when the engine is cold (like after work) and after the engine has warmed fully (like stopping at a convenience store after driving for awhile, etc.)
The ONLY time it happens (at least for me) is gas station restarts and the only thing that's different about them is that I've removed the gas cap. I'm in New Jersey and when we go through inspection, they specifically vacuum test your gas cap (I didn't even know they did this until I failed last year for a bad gas cap on another car). I'm guessing that certain cars are designed to have "sealed" (non-venting caps) and vice versa. I'm not sure which we have, though I would think that the point of an emissions evaporative system would be to NOT let the gas vapors escape out the cap, but rather to force them to vent into a charcoal canister and then get sucked back into the intake air stream somehow later (like my old GMs did). I can't quite figure out why a vented cap would be a good thing, but there are a lot of them out there, so there must be a good reason for them. In any event, I still say it's coincidental that the problem only happens when the gas cap is disturbed- everything else (including the charcoal canister, injectors, fuel filter, etc.) doesn't change during my "non-gas-station" start-ups.
Since it's cheap enough to test (I would hope), I'll try another gas cap and let you know if it does anything.
Keep me posted on your progress and thanks for your input!

I have a 2003 Santa Fe and have the exact same problem as everyone else seems to have.
I too have not brought it in for service yet. I realize this thread hasn't been updated in several months, but I was hoping somebody has something new to add.
All I can add is two things to do in the meantime:
1. When you start the car after gassing up, give it a lot of gas. The car will rev up and after a few seconds, throw it into drive. If you have enough room to go for a while without stopping, it should be ok. I've been filling up late at night when the stations aren't crowded to do this.
2. Leave the car running while you gas up. Obviously this is something you're not supposd to do, but it can work. The first time I did it, the car did sputter out and die while gassing up. But I tried it again recently and the car stayed running and I was able to drive off without a problem.

Well I finally broke down and brought the car to the dealer over this problem. I'm picking it up tonight, but he told me he replaced the Purge Control Valve. He seemed to jump on this as soon as he heard the problem. Good News: it was covered under the warranty (bumper-to-bumper, I believe, so you better check it out before 60,000 miles... actually I think it might be 50,000 miles depending on your year- the 2002s got a class action settlement for the brochure misstating the horsepower & we got the option of an extra 10,000 on the bumper-to-bumper... bottom line is try to beat the clock and it should be covered. After I pick the car up, I'll let you know if it actually worked...
