this is a new used truck to me.it starts fine idles fine and about 10 minutes later it starts missing at idle and then shuts off.it will start right back up and do the same thing.i can keep pumping the pedal (it is still missing) untill it reaches about 2,000 rpms and it will smooth out.does the same thing on both tanks.any ideas?thanks

Pumping the pedal does nothing on a diesel.
Might be ICP, try unpluging it and see what it does.
