Z28 LT1. Why do fuel injectors shut off?

it could be a wiring problem in the circuit or the injectors have a resistance problem or maybe even the injector drivers in the computer have a problem or are bad.

No fuel in one cylinder 1998 ford ranger

Either has a bad injector or the wiring to that particular injector has been pinched or skinned and grounded somewhere.

My van wont start no fuel or spark ?

Sounds like it could be the ignition module in the distributor. You have a throttle body instead of a carb. The injectors get a ground signal from the engine computer when they are supposed to open. The ignition module takes a signal from the pickup coil in the bottom of the distributor and decides when to fire the plugs and also the injectors.
If the injectors and the coil has power, it could be the module or the pickup coil.

My engine shakes when in park or when stopped for a red light and sometime shuts off

Sounds like the Engine mounts need to be checked, and/or it has intermittent firing on one or more cylinders. Could be the spark plugs and/or the Fuel injectors need to be cleaned. As the Engine somtimes shuts down, I would suspect the plugs or injectors.

Fuel injectors

I doubt it.
The injectors get power from a fused circuit when the key is on.
Then the engine computer grounds each injector when it wants the injector to open.
You would first need to know if the injectors have power, then if they are getting a ground signal from the computer when the engine is cranked.

96 maxima is shutting off without warning and takes a while to start up. Why?

When it fails to start you will need to determine if it is because of lack of fuel to the injectors or lack of spark to the plugs to proceed.
You can check the computer for trouble codes too.

I have a 91 chevry lumina 3.1 v6 i put and new fuel pump and filter and relay and check the coils they are fine i can start it it will run for about 5 mins and stops then restart fine and dose it again...

You've done well by ruling out the most likely things first. You need to next check the condition of the "ignition module". When this module starts to heat up, if bad, it will cause the engine to shut down rather quickly.

No power to fuel injectors on my 2002 chevy mailbu ls? replaced cam sensor, checked all fuses, new fuel pump.Had good fuel pressure and will run on starting fluid?

There is a fuse for ther injectors. There should be a constant power to the injectors. the computer is what grounds them out. So it's not the computer. Also check the asd relay. Auto shut down.

Slow start, has new battery, clean injectors, loss of power on hot days (will shut down and coast to a stop)

Bad fuel pump,a possible, on the shutting off issue.
Loss of power, most likely a separate issue.
Need a clean fuel filter. It should last two or three years or 30,000 miles though.

I dont believe it to be your computer now a relay sounds like stuck open these are simple to diy yourself under hood theres a fuse box relay pannel find the relay marked fuel pump now check other relays to see if the numbers match switch relays by pulling out basically trading spots if problem goes away just need relay replacement

Also have your car taken in for a free inspection could be a bad fuel pump or alternator getting ready to pass on check always basic things first spark ignition fuel and exhaust if runs you know one of these are failing do to maintenance
