Odd issue, stumped!

The other day I was driving my truck ( it was tuned on xtreme race) and i noticed something funny. As I barely mashed the accelerator it would do nothing then the power would come on all of a sudden. It seemed like when it was coasting the rpms were really low. So I shut the truck off and cranked it back up. It fired up but the rpms were really low for a few seconds and then it would idle up to normal. Then after 30 seconds or so the rpms would go way down and then back up. So I then tuned the truck back to stock. It acted the same way on start up. So I drove it home and It seemed to go away after a few miles. Now It starts and seems fine. I also checked the oil when I got home and It wouldnt even touch the dipstick, which it is due for a change. Any ideas? Trash in the fuel, water in the fuel, or because the oil was low?Also any idea where the oil went? It doesnt seem to be leaking any.

Three common places to check:
1. The degas bottle - indicating an oil cooler leak
2. The exhaust pipe (disconnect from the turbo) - indicating a turbo seal leak
3. For 2003 and early 04 model years (clearly not your issue) - the ICP sensor/connector behind and below the turbo.

There are MANY more places for oil leaks, but to show up as low level requires somewhat larger leak rate.

BTW - how many miles do you go between oil changes?

I usually go about 5k. I had a new oil cooler put in about a year ago. Would the low oil level explain what happened?

No but the links in my signature will.
