hiccup or chug and stall at idle

[PolarBear]

So I've been my driving my new to me 01 F250 4x4 auto and 2 mornings ago it stalled while leaving a stop light. I threw it in neutral, turned the key and it fired right up and kept going. I then put a new CPS in from the International dealer, dark gray one with the blue O ring. Truck seemed to run better and hasn't stalled while driving since. This morning while sitting and idleing before work the truck just died. Restarted it, and about 5 minutes later it kind of made a hiccup or a chug for just a split second. The lights on the dash all came on like it was going to stall, but the engine kept running and the lights went away. It did the same thing a few minutes later but never did die again. I have drained the fuel bowl twice. The truck has a fairly new fuel filter in it, but I believe this truck probably set on the dealer's lot for probably at least a couple months. Thinking of changing it again and checking for any debris in the bowl. It always starts and runs great, all fluids fresh. Any help would be appreciated as I'm 1800 miles from home for work and don't have many tools with me.

Anyone have any ideas on this? Saturday I changed the fuel filter and poured in a bottle of Seafoam with. The fuel bowl was pretty dirty so I cleaned it up nice. I thought that was the fix since the truck ran great from Saturday until this morning. After driving just fine for 25 minutes, when I got on the gas to leave a stop light it died. Then after idling for about 5 minutes when I got to work it died. No rough idle or any indication at all. I'm pretty sure a dealer would want an arm and a leg to try and diagnose this too and it probably wouldn't even duplicate the problem.

it sounds to me like the fuel pump may be kraping. But you should try and get it on a scanner.

I'm working on trying to find a scan tool out here. Do you think a fuel pressure check would show if it is the pump about to go out or any other tests? I've tried lightly pushing and pulling on all the wire harnesses while its running to see if the might kill it but nothing ever happened. IPR doesn't seem loose at all either. Died twice in about a half mile on Friday and then idled fine for 20 minutes when I got to work. Definitely would like pinpoint this soon so I can start to mod this thing!
