my van was started and running all of a sudden it died it does not want to start again what could it be?

you don't just guess at it! TEST things first.or if plenty of money just start replacing parts! gotta have SPARK,so test for spark first.gotta have FUEL,so test the fuel pressure also,with a fuel pressure tester.don't ASSUME anything. FOUR different engines for that van,what size engine is it?
