Why would a 1989 cavalier z24 after getting warmed up the car start jerking and then stops?

Similar situation happened two separate occasions my cure was plugs & wires & then a distributor. Yes,that is one possibility.But,there are many things that would cause that.Low fuel pressure is another.Then it could be a crank sensor or a cam sensor. It could also be the ICM.When they get old or get to hot they will quit on you. But fuel pumps go out in many different ways.Such as melting plug, pump gives up after it warms up, and just going totally out and stop pumping.Before buying parts you dont need,check the fuel pressure.I once worked on a Ford Tempo with bad fuel pressure.After swaping 3 pumps,I found the bottom of the plastic bowl that it sits in would buckel up and press against the fuel inlet shutting off the fuel after the fuel in the tank got warm from the return line.
