I pulled the IAC valve and cleaned it with choke cleaner, No luck. What about the fuel pump relay? Could that be overheating and shutting down causing me not to get fuel. It does feel like I'm running out of fuel before it stalls.

 

Have you been able to determine if you are loosing spark or fuel pressure after it stalls and will not start untill cools down for 5 minutes???
The fuel pump relay is in the underdash fuse/relay box and is labeled CIRCUIT on the location diagram imprinted onto the under side of the box cover.

 

Don't know if it's spark or fuel loss. I replaced the fuel pump relay. That hasn't helped either.It's very frustrating to me. I've spent over $500 on this car in the 2 months thatI've had it.I'm stumped. Thanks for all the replies.

 

It's now overheating! We pulled the thermastat and that hasn't helped. Now what? It's still overheating.

 

Are the cooling fans coming on? If they are but is still overheating then, disconnect the fan connectors so you can reach a hand down in there without possibility of them coming on. Let engine run untill it just begins to overheat and then reach down and carefullyplace your hand on as much of the radiator surface as you can thru the fans. Carefull as it may be very hot. Radiator surface should be hot across the entire surface. Lower area should be slightly cooler but probably will not be able to feel this with just your hand. Non-contact thermometer works great for this. If you feel cool or cold areas then your radiator is restricted. If top tank and entire radiator is cold then could still be a very badly restricted radiator but would more suspect that hot coolant is not being pumped to the radiator from a possible failed water pump of belt missing.

 

The fans are working. We also flushed the fluid and put new in.We are going to try the the water pump. Do you think that could have been why the car was stalling when it was getting hot?

 

Turns out, the alternator belt that I just had replaced broke. What would cause that?

 

Did you find an answer to the stalling when hot? I have the same issue in my 323 Astina 2000 manual. I have replaced the MAF, fuel pump, fuel filter and the crank angle sensor. Need help as its intermittent and it will start after 5 minutes.

 

 

I found the issue it was the cam sensor. It hasn't had a problem since. Hope this helps you
