The van will die at highway speeds with no warning. First time was three years ago. Then about a year later,now every 2 to 3 months. It acts like its running out of gas. Let it set for about 30 minutes it will run fine. Nothing is set in the computer,the feul pump checks out good. (they ran it for 2 hours with no pressure change)
Thank you dan2oaks

 

Did you ever find the problem ?
I have a `94 that occasionally, without warning, just
shuts off too. I can restart by shifting to neutral
while still moving.

 

I have not found the problem yet.
