89 S-10 starts runs for about 30 sec then dies. But will start right back up and do the same

I have a 1989 s10 with a 2.5 and a 5 speed. I just replaced the clutch, slave cylinder & clutch master cylinder. After the repair the truck started and ran fine, it made a two hour drive then the next day it would start and run smooth for about 30sec then die like you just shut the key off. It will start right back up but does the same thing. It reads no coads. All wires that were unhooked when replacing the cluthch were hooked back up. Any ideas on what could cause this?

it has a new pump and filter, there not brand new but only a few months old. I can watch the injecton on top of the throtle body spray fuel while its running and while its dieing.
