HELP!! randomly drops to idle while driving?!?!?!?!!!!!!

so my truck just started acting up....
2005 5.9 auto 95,000 miles
when cruising or mild acceleration on normal roads the truck will repeatedly drop to about 800 rpm and after 2 seconds resume back to normal. its completely random and constantly does it on back roads and driving in town but NEVER does it on the high way or accelerating hard. what the hell is going on???

Do you have any chips or boxes?

Have you checked for error codes with the key off/on three times trick?

Sounds like an APPS (Accelerator Pedal Position Sensor) issue.
