I turn on the engine, I drive a few minutes and then the engine turns off. My car does that constantly. I want to kn what would be the possible cause for my car to do that? I was told that it is an electrical problem but I don't know. In my country we don't have good electrical mechanics and I need your advice on this situation before I make a move to take my car to someone.
Do you
have the same problem?

This is a real common problem on all car brands and models. A sensor fails when it gets warm, then works again when it cools down. Most of the time there will be a diagnostic fault code stored in the Engine Computer related to the failed circuit. If there is not, your mechanic can connect a scanner to view live data during a test-drive. That will show which sensor signal is dropping out or missing when the stalling occurs. Be aware a sensor is only the cause of the problem about half of the time. At other times the wiring to that sensor could have the problem. The fault code only indicates which circuit needs further diagnosis.

I have a 1995 version of this car but I don't think the computers on these cars are that advanced or so I've been told by mechanics it pre dates any OBD interface? If that is not true please explain? Can I go buy a scanner? How would I connect it? I have the exact same problem.

You should start a new question. When you piggyback on an old one, no one other than me will see it and have a chance to respond. That does you a disservice.

The only difference with your Engine Computer and the '96 and newer ones is the newer ones watch an oxygen sensor after the catalytic converter in addition to the one ahead of it. The '96 cars and light trucks sold in the U.S. Use the OBD2 (on-board diagnostics version 2) emissions system. Also, the plug under the dash was standardized. Some of the terminals are still manufacturer-specific.

Viewing live data goes back to 1983 on Chrysler products. You have that capability on your car too. The issue isn't the car; it's the scanner. I use Chrysler's DRB3. The newer models only work back to 1998 models, but with an additional plug-in card, they work back to 1994 models, AND will do emissions-related stuff on any brand of car 1996 and newer. With a different card, it will work back to 1983 Chrysler models.

A less expensive alternative is the older DRB2. That one uses plug-in cartridges for the various applications so you have to be sure you have the cartridge that covers your car model and year. The DRB2 only works on Chrysler products. You'll probably find these on eBay for under a hundred bucks. I have two of them. I also have an older Monitor 4000. It was made by the same company that made the DRB2 for Chrysler, and looks very similar. It also uses cartridges but they're different than those used with the DRB2.
