My 93 blazer dies while i am driving. It just shuts off and the brake sticks to the floor, i lose my steering, and my battery light comes on. When it dies the radio is still playing. i turn off the truck and let it sit there for a couple of minutes it starts back up then dies again. If i let it sit for a few hours its starts up like nothing happened. This has happened to me twice in three . Please can someone tell me what is going on.

 

I'd say check your ignition coil, ignition control module, distributor cap, rotor, and fuel filter.

Sometimes when the truck gets hot, all the trash in that filter will gum it up. Next time it does it, tap on the filter and the bottom of the gas tank and see if that makes a difference.

While the truck's running, carefully pull the boot off of the coil wire and see if the coil is firing, if it is, make sure it's a white/blue spark and not red.

The ignition control module will also cut the truck off when it gets hot if it starts to go bad. Those can be tested at your local AutoZone, just have to get to it. It's plugged into the top of the distributor.

Those are all places that I'd start. Start small and work your way up.

 

I am thinking it is your fuel pressure regulator.
You brakes, battery light, and power steering do what they do becuase the engine died.

10 to 1 says you don;t have any codes either. How much mechanical skill do you have? If not much, might want a shop to do this one.
