Same thing happened to my wifes car, But I had no issue other than a error code about not reading the ECU, The dealer replaced the ECU and the thingy for the key fods , Dont remember the name of it ( Was two years ago), They gave her a hard time but she only had 800 miles on the car so they repalced it under warrenty, They told he it would have been like $2500 to fix, I had a huge thread about it, Sorry this happened man, FYI Dump the HT also, I'm almost 100% sure you losing power.. I had a huge thread on this also , I actualy lost WHP with the HT.
