yes the fuel filter has been changed, also when the van dies, we do not have spark to the plugs or coil (new coil) and we dont hear the fuel pump either, as already said it will start again after it sets for 20 to 30 min.also no codes out of it,either
Thanks
Thanks

My first guess would be something that would affect both spark and signal to fuel pump.....Try a faulty ignition switch or relay....
the fuel pump relay and ignition relay are the same. swap them. if it happens again but this time its fuel that quits then its the relay....

Under the hood by the master cylinder there is a long black fuse block. Underside of the lid has the locations of whats what. The fuel and starter relays are side by side. Also, try the gear shift. Wiggle it while its running to see if it kills the engine. The neutral start switch could be off. it might think its in reverse.

ok, but the fuel pump relay is five prong and the starter relay is four, will that work and if it will, i will try the wiggling at the same time and get back to you

Iswitched the relays, and ran vehicle for two hours, all good, but when i shut it down and tried to recrank, it would not start, swapped relays back around and it fired back up and ran, so what do you think about this, the wiggle with the gear shift had no effect

Replace the relay that you put in the starter position.....or both since they are not too expensive. The two relays have the same number on the back right? They do on my 2002. At least you can eliminate the relays if new, and then see if it has any issues after. Any codes?

when running the van yesterday, felt the relay for extreme heat, while touching the relay, it would click under my fingers, and already installed pigtail installation and running the van to see if it keeps running, will let you know what happens
Thanks
