Could be as easy as a bad battery connection. Mine did the same thing. I would have occasional stall issues just out of the blue.It just kept getting worse over a couple of month time period until finaly it wouldn?t turn over anymore. I ended up replacing my ignition cylinder lock with pass lock sensor on my 2000. Not to be confused with ignition switch. Dealer says they replace a lot of the ignition cylinder locks. I guess the pass lock sensors go bad? Since pass lock sensor is part of the theft system and decides if your car ?should? be running or not. Usually the dealer will replace both the lock cylinder and the switch at the same time. This seems to be a dealer only item. Since the dealer has to reprogram your cars computer to accept the new lock cylinder. So far so good on mine anyway. Rich Something else to consider: Also, check the Fuel Pump Relay. On most Oldsmobiles, these relays are located behind the right headlight. Often there are four or five of these and they use the same part number so you can exchange them with each other and likely move the problem to something else like the AC blower fan. If the engine is stalling, stalls or dies but will restart easily, the fuel pump relay is likely to be the problem. This problem can also show up if the engine tends to die on a right hand turn or when applying the brakes and comming to a normal stop. This usually will not happen during hard acceleration. This Fuel Pump Relay problem will not set any OBD or OBD2 codes for the computer. This certainly applied to my 1996 Oldsmobile cutless ciera with the 3100 engine. If the AC blower motor relay is bad, you will often loose the slower speeds for the fan. The high speed fan will work but nothing below that. Good Luck! Mark,

If it is happening when the engine is warmed up and it won't start again until it cools, it could possibly be vapor lock. Make sure the fuel lines aren't running too close to the exhaust, or resting against any part of the engine. If temperature isn't an issue, then check the fuel filter and fuel pump.

What does it mean when after a car runs hot and stalls it don't start up again?

Engines do not tolerate overheating. Often a head will warp slightly when the engine overheats and the head and/or engine block can even crack. Run a compression test on the engine. If you have a couple cylinders with low compression, the overheating has caused significant damage.
