Once my 98 lumina gets to normal running temperature it stalls out but it doesent spit and sputter it shuts off like somone turned the key off i have replaced fuel filter,iac,plugs&wires,ignition control module,starter,battery,but still stalls out but when the temp gauge says its cool it wont stall it only stalls when it gets half way up on temp gauge i've checked fuel pump and fuel pressure and they're both fine i'm between a rock and a hard place and could use a lil bit of info as to where to go from here
If you think you have a problem with intermittent rpm signal, check the crank sensor. Any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.
Connect a scan tool to the car and check for DTC codes. If the car stalls likely a check engine code is set.
Your friendly auto parts stores will provide this as a complementary service.
Since the engine is computer controlled when this happens it should set a fault code in the memory of the computer control module, to retrieve this fault code you need the system scanned, it is called an "OBD2 Fault Code Test" Any Autozone or O'rielly auto parts will do this scan for free. Then post the results here. DO NOT TAKE ANY ADVICE FROM THE PARTS COUNTER FOLKS AT THE STORE, THEY ARE NOT TRAINED TECHS..

It could be caused by a bad sensor. You need to scan it when it stalls and won't restart. Most common one to go when hot is the crank position sensor. Make sure the vacuum hose to the MAP sensor isn't clogged or leaking. It could be the fuel pump as they run hot and stop, then start working again when cooled down. Next time it stalls and won't restart try using starting fluid. If it starts then it's probably a bad fuel pump. If it doesn't start pour some cold water over where the crank position sensor is located and try starting it. Again if it starts now you know what to replace.
Testimonial: "great suggestion i can do that right in my driveway.thanks"

loose vacuum line, check for same, also check the map sensor and the measure the fuel pressure, make sure its at spec
Hello
The engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
