Truck runs good for 10 mins, then stalls. on 1991 Dodge D250

What is in the distributer than controls how much air/fuel mixture to send to injectors. It seems to be sending too much fuel, after truck is warmed up.

could be an ign module when it stalls check for spark and fuel pressure

we did check for spark and a couple times there was no spark, and sometimes there would be, but injectors seem to be still shooting fuel in when key is on but not started

sounds like you have a bad ign module
