Purchased my SRT6 about 3 months ago. Very nice car, yes, very happy with it. Well about two months ago, it would crank but no start. CPS, I assumed so I picked one up at the dealership, changed it out. The first time I started it, it died on me, thought it was a fluke so ignored it. A few days later, it cranks but no start. I tried to repair the RCM but kinda gouged it in the process of removing it. So i reinstalled it, didnt start, also no fuel. So I assumed because the car had been sitting for several months before I purchased it, that the fuel filter may be clogged. Changed that, it was in fact clogged. Car started but no throttle response, mechanic friend recommended the fuel pump which I changed, still a rough idle with no throttle response.

Eventually I finally decided to take the risk and purchase a new RCM from the dealer at a discounted price (lucky me) and the car started up no problem. Drove great for about a month, then yesterday I drove it a very short distance and it stalled on me six times. Car died and luckily started right back up when cranked. I tried it this morning and it starts fine, no problems that I can see. Now my question is, what could it be? I changed the battery as well two months ago.

Note, I have not soldered the RCM yet would that cause that?

Any help would be greatly appreciated.
