2007 dodge ram 2500 stall

2007 dodge ram 2500 5.7 will be running and just stall. just like you shut the key off. if you hit the key it starts right back up. I scoped the cmp,ckp,injector control and coil control. what I found is the ckp would glitch then it stalls. only 1 little glitch. right after that no injector or coil control. checked ground at the ckp when it happens and its good. so I changed the ckp sensor and pig tail (didn't look to good) started it and ran it for 4 hrs do stall great fix this was Friday now today I get a call it's doing it again. or maybe still I don't know. I don't have it back yet so I haven't done any checks but it sounds like it's doing the same. when I scoped it last time the ckp would seam to mess up at the same place in the pattern. seams strange to me as it reads off the crank. I don't see how there could be a problem there. I sent a pico file of it when it happens. thanks in advance all.

I would pull the sensor and do a visual inspection (using a bore scope, if needed) of the reluctor, while turning the engine by hand.

that's what I was thinking. would one skip in the ckp signal shut it down like that? I would think it might cause a stumble but not a stall. I'm not that familiar with dodge strategy. is the reluctor just notches in the crank on that? thanks for the input

I wouldn't think so, but I couldn't say for sure. Hopefully, some of the others will be chiming in, soon.

A google image search came up with this.

I have the same problem on a 2005 Magnum 5.7. Started as customer saying he got battery relplaced, now it stalls every so often. When I got to it, it had only 4 codes, all 4 o2 heater circuit high codes, and hesitant start up. Checked out the heater circuits and everthing fine. Found dirty TB, cleaned it and it started much better with a rev flare and comes back down stable. Thought I was done. Test drove 2 miles and it stalled pulling back into the lot. Found that if i turned key off, it would start everytime. After a few days of testing Now it is a crank/ no start before I replaced anything. Found ckp glitching, so I pulled the ckp sensor out and had someone spin crankshaft by hand while I looked at the reluctor teeth. Everything looked good, so I replaced ckp and cmp. Yesterday after the ckp replacement I got a beautiul ckp signal with consistent spark, but no inj pulse. Today in morning back to a glitching ckp, inconsistent soark, no inj control. I have sensor voltage ref and APP codes. Both ref are 4.99 V, app 1 and 2 data PIDs change when I move pedal. I unplugged and checked V ref at the APP. It uses both ref 1 and 2, and they were both 4.99. Read a common issue is OPS brings ref down, but it had 4.99 on OPS plugged in and unplugging it changed nothing. Now it has a throttle cant close p2111 code so seems like it jus keeps getting worse. Yesterday I thought maybe pcm thinks its in clear flood mode but today I dont have consistent spark again either. But I smell fuel at tailpipe. Im gonna make my own post on here so hopefully well get both of these knocked out.
