It sounds like a fuel filter may need replaced or the fuel pressure regulator needs replaced.

SOURCE: 1998 Chev Malibu starts then stalls

The most likely cause for the problem you are describing is the anti-theft system. GM calls it a passlock system. Your car has a 'key-reader' mounted on the ignition lock cylinder (inside the steering columnm, or inside the dash, depending on where your key goes). This 'key-reader' sends out a signal to the body control module indicating that the proper key is in the ignition. Note: this style antitheft system does not have 'chip' in the key. These key-readers fail frequently and send a an incorrect singal the the module, where the car will start and run for a few seconds, then stall. An easy verification of this problem is to watch for your security light to be flashing somewhere on your dash. The passlock cylinder is only available from the dealer, and while it is a fairly easy part for someone like me to change, I do not recommend it for someone who is not a mechanic. Additionally, even if you do change the passlock cylinder, you have to perform a re-learn procedure or the car will never start. This probably isn't the answer you wanted to hear, but better that you know. Hope this helps!

Well the only thing i can think of is when your fuel is below half a tank the pressure relief valve and a rubber hose between the pump and the fuel line is exposed. Its possible your fuel is leaking back into the gas tank as it sits overnight, ect. You may want to perform a fuel pressure check when the the gas is at 1/4 tank and been sitting for awhile, pressure should hit 55 seconds after key is turned to run position.

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.

When I start my car with the remote, the doors don't stay locked. Any ideas?

High dollar aftermarket remote start systems last about 5 years. Cheaper ones, lucky to get 2 years. They cause all kinds of problem when they get older, your's is one. Others are no start, doors lock and unlock by them selves, Car starts by itself..Tear it out. One wire at a time. Repair any wires that were cut as you go. If you don't. Someday soon your car won't even start with the key. Security..

Hi. It would be useful to get a code read and some live data from a decent diagnostic tool. There are quite a few possible causes including, pressure in tank - if the fuel tank can't vent pressure then a vacuum will eventually form stopping fuel getting to the engine, this will cause it to loose power and stall. Then after a few mins the pressure will drop and the process start again, easy test is when the car stalls remove filler cap - if that's the fault there will be an audible hiss and the car will start up again.

part blocked exhaust will have same problems but will more generally cause a lack of power and acceleration.
are there other symptoms? i.e only when conering or only when pulling off or stopping, engine light on/off. Jon
