I have an 04alero, it will start and shuts off right away

When you say right away....it is as soon as the vehicle starts....or is it 10-15-30 seconds later? Is this a factory remote start? If not, and you installed an aftermarket one, what is probably occurring is that your factory anti-theft system is seeing the vehicle running without the key in the ignition and activates the immobilizer which shuts down the vehicle. Aftermarket remote starts require adapter electronics to bypass the immobilizer until the operator enters the vehicle and inserts the key. This is why most aftermarket alarm systems are installed by trained pros.

sounds like the regulator is bad in the altenator. Start vehicle and disconnect negative cable from battery. If it stays running you have another problem. If it stalls out right away the altenator isnt working.

Fuel Pump--most likely

The ignition module would be the first thing to change out,it is most likely the problem.

car starts and idles good.it cuts off while driving,and starts right back up????????

CHECK THE CONDITION OF THE BATTERY CHANGE IF NEED BE

my dad had this problem with his ram. it started having problems like yours, starting right back up. but after a few month of this, it woudn't start back up and the display read "no bus". it turned out to be a bad computer. he had to replace it.

this sounds like a defective fuel pump, but u will need to have the fuel pressure tested when it acts up to verify this is the issue 100%, the fuel pump is located inside the fuel tank.

what that means is your engine goes into protection mode and shut's off this is mostlikel;y do due to low coolant level or low oil level/pressure. have this checked by a qualified tech. diagnostic equipment must be used to clear the code after the problem is solved in order for your vehicle to run properly
