Respuesta a "Why would my van starts but shuts down after a few seconds?"Sounds like you've triggered the security system which I have done on my own 1999 T&C LXI. To reset first you have to be OUT of the seat. Next use remote fob to lock then unlock and do this a couple times to make sure you have fixed the ignition starting/running problem. It's easy to do this in several configurations, especially when dealing with battery, fuse, selenoid trouble shooting . If you unlock it manually and get in the seat you've triggered the alarm and must reset it so it will run.
