After diving 20 minutes and the engines gets hot, my blazer loses power and cuts off. It is also doing this after sitting at a stop light or stop sign. This happened after I replaced my battery and alternator.

I just replaced the spark plugs, #5 spark wire and fuel fliter.. My mechanic checked ignition switch, coil, O2 sensor, MAP sensor, Mass sensor and said all of those things were ok. He thought the remanufactured alternator was bad so I installed another remanufactured alternator and an alternator belt and still having problems.

Hello, are all the battery and alternator connections/wiring circuits, ok? Does it restart immediately after it stalls?

Yes all of the wires to the battery and alternator are ok. The vehicle does start back up immediately after it shuts off.

How is the fuel pressure? If the vehicle doesn't act up long enough to do any testing, it's like hunting a needle in a haystack. You could hook up a fuel pressure gage, let it idle till it dies, see if the pressure holds.
