You need to isolate the problem. Test fuel pressure. If fuel pressure is above 25psi, ur problem is not gas related.Check spark at the plugs if spark is normal, test to see if it's sparking on time, when piston is TDC or do a compression test to check if the timing is ok.

I have spark it did this a week ago cahnge out everything fuel related and it stopped now its doing it again
Check the plug connector at the pump on top of fuel tank, I had one that wires were corroded and was doing it intermittently

That wut i was thinking. Disconected everything car runs off brake cleaner so im thinking it is a faulty fuel pump
Well, it fuel related, now u gotta check voltage to the pump befire u replace it. If there's voltage at the pump and it doesn't work, then it's the pump or strainer on the pump, assuming there's fuel in the tank lol
