After i start my van it runs maybe 1 minute then stalls out

Hello, 'Start and stall' issues can be one of the most difficult to figure out. If it runs for a full minute before shutting down, it sounds like the issue occurs when the engine idles down (decreased fuel). In any case, I'm sorry to say you will probably need the help of a professional technician with diagnostic scanning equipment and a short list of hands-on diagnostic tools (fuel pressure gauge, smoke machine, etc..) I highly advise against buying parts for the van in attempt to fix it, that typically wastes time and money.
