Car shuts of suddenly while driving. Starts back up after 20 minutes.

When the gas-cap is plugged, you build up vacuum in the gas- tank and cause the gas flow to stop.
Use premium gas only, ETHANOL in the mix is attracting moisture/water which is part of the problems.

I have a 1997 Chrysler Sebring 6 cylinder 2.5 it's been missing and will die when it I drive it for to long could be a pick up coil auto zone shows it as a distributor pickup I have replaced plugs wires...

Night be vapor locked..What's that? It when your gas tank pressure becomes greater than your gas pump...You'll be driving then it just shuts off like running out if gas... Quick fix? Open your gas cap and leave it Lise to get air into your gas tank..Clue if this is the problem...Your car will start immediately. Hints...Listen when you loosen gas cap...Can you hear air sucking back into your gas tank. Cheap fix..Take the smallest drill bit and drill a hole into the center of the gas tank..It also could be a replacement gas cap that someone put on the car..Buy the original cap..What caused the problem to start with? Over filling your gas tankk..Putting that extra 75cent to top it off..Your cars gas tank is designed to burn fumes...When you over fill a tank it sends gasoline down those vapor hoses then into a charcoal canister..Over years if doing this...It gets clogged up then the fumes can't get out the tank...It builds up pressure and becomes greater than your gas pump...Then it shuts off...If you wait long will start back...This sounds crazy....But this could really be your problem...Next time the car shuts off... loosen gas car...If it starts...BINGO....You have solved your problem... Drill a hole in gas cap or buy another canister... Usually behind the headlights... Some under car..Follow the gas line... Hope this helps you or someone else....Stop over filling your gas tanks...You'll keep this from happening....Tell others

GASCAP and engine light

A bad gas cap will cause the light to come on, of so replace the cap. The vent is not working if gas is coming back at you. Replace with new.

I have a 2005 vw jetta an I changed fuel pump fuel filter an it keeps vapor locking on me it will drive for about a hour n the heat an then it will start jerking an shut off at a stop light then i will...

The problem could be a clogged air vent in the gas cap, causing a vacuum in the gas tank . The next time this happens, loosen the gas cap and see if the problem goes away. If so, replace the gas cap.

1995 Firebird After Running Low on Gas

You have most likely sucked residue in the bottom of the fuel tank into your fuel filter, This can cause it to get blocked, Try fitting a replacement fuel filter as it's most likely it's never been changed anyway.

Sounds like water/debris in the gas tank. Try adding dry gas to the tank. Changing the fuel filter also a good idea.

2002 Grand Am

a P0442 would be a small evaportive emissons leak. The code would help. Generally a small emisson leak is a faulty gas cap. I would make sure that the gas cap is tight and that it is seating properly. For the $$ I would go buy a new one, but from GM only as aftermarket caps cause more problems then they solve. If you left your gas cap off for some time. I would just replace it and drive it for 3 cold starts and see if the light goes away. You can not reset the CEL from the fuse panel. unhooking the battery will do it but it will also reset all emissons monitors. I suggest you drive it with a new or tightned fuel cap and we can go from there.
