I found this to be just dumb enough and funny to share:
Customer had his 2013 Challenger towed in. He said it stalled without warning and wouldn't restart. Got it in, pulled codes, found ASD relay circuit low. Found the circuit wire and sure enough it was shorted to ground. UNTIL the TIPM was unplugged. What in the actual??
After much back tracing and cursing, the culprit ended up being a shorted washer pump. It back fed through the control circuit which is also controlled by the TIPM and caused a chain reaction that geeked the PCM. You've got to be kidding me...
At least this job keeps you thinking on your toes once in a while!
