Does it have an IATC or idle control valve? Did you remove the battery cable for ten minutes,rehook it up,start it and let it idle for 5 min. and then drive it for 10 or more miles? That will reset the computer to your driving habits they tell me.
Now,cleaning the MAF sensor and installing a new air filter would be a good move.Do this before you unhook the battery to reset the computer.

Died on rd, replaced fuel pump, crank pos sensor, temp sensor. Still starts gets to operating temp then skips dies. Won't restart till cold then same thing

A bad thermostat leads to poor engine performance as it alters the engine's operating temperature greatly. Moreover, it could also lead to reduced gas mileage. God-Bless! It may be stuck closed, if this happens it will over heat. If the thermostat is stuck here, the radiator coolant would stop working, resulting in the car overheating.

Alero Problems car starts, but dies at running temp. then after 20 mins. it will restart, until running temp again, then dies. have changed, cam, crank, & map sensors, also ign. model, & pass lock assy....

Seems to me that I've run across this problem 3 or 4 times over the years on different cars. Problem usually comes down to either fuel system, electrical system (including sensors), or the coolant system (including sensors). I ran into this most recently on an '89 Escort. Wound up replacing fuel pump relay, ignition relay, TPS sensor, ignition module, coolant temp switch, coolant pump (and timing belt while I was in there). Fixed a couple of engine grounds and a couple of misc things. Point is that there is probably more than one item at fault.

1999 Chevy Blazer dies after it reaches operating temp. fuel pump is still running but no fuel to motor?

the only thing You can do is take a test light and check the grey wire at the fuel pump to see if you have power while someone cranks the engine. If so replace the fuel pump. If not replace the fuel pump relay. Hope this helps , leave a comment.

I have spark on all 6 cylinders i just swapped out engines and i'm using the same fuel injectors,i can make the engine run on starting fluid

so your problem is little or no fuel pressure,
did the car run before you swapped engines?
if it did that would eliminate the fuel pump,
did you get the crank sensor and cam sensor reconnected,check the fuel pump fuse,and relay,

1997 F-350 Ford Powerstroke4x4 Crew Cab Diesel 83k miles. Truck runs fine while cold. When it starts reaching normal operating temp it starts missing and loosing power when accelerating. Truck idles fine....

Have you changed your oil? Rotella 15W-40. These engines really don't like old oil. It becomes too thick for the injection pump to work correctly. Another possibility is a bad cam sensor on the front of the motor. Most engines call this the crank sensor but on this engine you have to look it up as a cam sensor.
