All three flashed across back to back he said and the truck had reduced power as if the traction control was kicked in. any ideas? truck is long out of warranty

Got to get those code(s) pulled.

pulled the code with my insight and i get a U0101 code, which is pointing towards a TCM issue

I think TCM issue is a common things on the early year LMLs. I recall a thread on something just like this.

Yep! That's TCM issue. If you can wait, order the part through Rock Auto and then take it to either a dealer or a mechanic that has a Tech II to program it. The dealer wants over $600 for the module and for the same item R/A only wants $300. Mine went out on a Friday afternoon and cost me over $1000 to get it done that afternoon. I'd try a private diesel mechanic that you trust first for the programming, if you don't have one go to the dealer. They shouldn't charge you more than $200 to program it.

Good luck.
