Could be several things, overboost, EOT too high, failed sensors. If you were to google "6.0 powerstroke limp mode", you'll get a whole bunch of reading material.
Your best bet would be to first check if there are any stored codes. Try to get a good code reader, all code readers are not created equal. Some of the cheaper code readers won't read the "harder" codes.
If you don't find any codes that could of caused the "limp mode", then I would suggest clearing the codes, and try using a diagnostic scan tool that can read live data and go for a drive with a load on, try to reproduce the limp mode while monitoring the live data.
