TBI won't stay running? Help ASAP

[grtwhite]

Have a 87 K3500. Truck starts hard & runs rough for about 30 seconds then cuts out. Fuel delivery stops. I'm able to keep running on ether. I'm thinking it may be IAC sensor? Forgot to check the code. Truck died in a parking lot & left me stranded. Thanks for the help!

really could use more info, but my bet is that your fuel pump took a dump

Could also be your distributor module. Can you hear your fuel pump run for a few seconds when you turn the ign to on?
If the dist module is bad it will stop fuel delivery to the injectors.
alao make your truck run like crap.
