Repeated SKREEM failure?

2005 SRT-6 with 68k miles.
No recent modification, service, problems. Runs well with no issues, no check engine lights. The last things I did were recover the headliner last summer, oil change in fall.
Crank position sensor went in 2013 and was changed to OEM.
RCM failed in 2014 and was replaced. I actually just swapped to another known good one as well, no difference.
SKREEM failed 09/2015 and was replaced by dealer.
The car has some bolt ons and custom tune from eurocharged, has been running great that way for years. Passes smog fine.

Today it has classic SKREEM symptoms - three starts/dies, won't crank after this. Disconnect battery and this cycle repeats.

The key fobs all function to unlock the doors, have new batteries.

I can't believe this thing could fail again after two years! I ordered one from needswings since that'll save me a lot of time trying to get the dealer to replace it, but is it tough to do yourself? Thanks guys.
