help code 2509 and truck just shuts off
 

Got a 2007 3500 megacab with the 6.7 and all deletes with h@s truck has ran perfect for years like this but it has shut down on me 4-5 times and if you wait 30 min it will fire right up but when it does this the temp gauge goes to 0 and the starter wont work either. Batteries are new and all cables are good I am thinking that the tipm module is going bad anybody had this issue.
