Engine Performance problem
1994 Ford Tempo 4 cyl Two Wheel Drive Automatic 107.00 miles
My car dies while I'm driving it, for about 30 min.
It only does this when it is hot or humid outside. I have owned this car for a few yrs. Now with very little problems. I've had 3 people tell me that it is the Camshaft Pos Sensor so I went ant purchased one, even though I have not been lucky enough to have someone find out where it is located. Anyway I just had a gentleman tell me that thats not what the problem is. All I do no is that it really, really sucks to keep getting stranded and then have to sit for at least 25 min. Before it(might) run again, for just a little while.I work 2 jobs, and have an 11 yr. Old daughter and unfortunatly don't have the extra cash to keep buying parts. Folks if anyone out there has ever experienced a similar problem, would you please, please let me know what this could be? Thank You, Rita

Next time it dies out don't wait do below immediately to determine if its fuel or spark problem.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

A typical but expensive for new part answer to your question is the ignition module is overheating and shutting down. Does the car's air conditioning work and do you use it? The ignition module is right in the path of the heat coming off radiator/condenser. Using the air increases this heat! There is a pickup coil in the distributor also that can be heat sensitive to failure.
The ignition module is located on outside lower part of distributor where the plug in is attached. The plug connects to it! I carry a spare spark plug for testing of ignition system on the road. I remove the coil wire in center of distributor cap and attach spark plug and lay on metal valve cover and get inside and try to start while watching plug for spark! You have to have plug situated so you can see the gap where spark jumps!
If no spark you could try to cool off module with water in a soaked rag holding against module for a minute or 2? Also when car quits, listen for 5 second fuel pump hum when you turn key just till dash warning lights come on(do not turn all the way to start) try listening for hum before this problem happens for practice.
