'04 Xfr (6-spd manual) started when cold and drove fine. Engine gets to operating temp then make a quick stop (5 maybe 10 minutes) and car would not turn over again. Let car cool down for 20 minutes and voila, started right back up. Googled around and all signs point to crankshaft position sensor (CPS). Chrysler Dealer quoted me $185 for the CPS and $65 labor, independent MBZ shop quoted me $300 - I looked around on the internet and found this Bosch CPS for $43. Looks like I'll do it myself in 20 minutes and save a bunch of $$$.
