Once you get it to die, you will need to be able to crank it, while checking for fuel pressure and spark. It sounds like it could be a fuel pump either getting hot and stopping or getting clogged momentarily, or something else electronic(like a distributor, ignition module, something like that) getting hot and not working for a period of time. If you can verify that you either don't have fuel pressure or spark after it has died, you know where to start looking.

Right, you need to find out if it is fuel or spark, the quickest way is to get it in failure, grab some starter fluid spray and spray some into the air intake if it fires and runs briefly then it is fuel, if not then it is spark.

Itll crank all when ever it dies and i can hear the pump winding when i turn the key on. The biggest thing is when it just cranks theres no fuel coming out of the throttle body. The inline filter is brand new.

Btw it just got new plugs wires and a distributor cap

The pump running is not necessarily indicative of fuel pressure. I agree with tennisshoes, hit it with some starting fluid to see if it fires, that'll verify spark anyway. If you have pressure, you will need to test fuel injector operation and signal
