Stalls before warm up even after running for 5 min every once in a while, also fired it up this morning and it was a crank no start, 10 min later it was fine. Getting misfires on the scanner. Throws an O2 error on the downstream but it's been doing that for a long time and goes out after a day or so, just have not gotten around to replacing it. This has been ongoing. So far the ECU replaced, CPS and the one in the dist, brand new battery, plugs cap rotor and wires less than a year old. It hiccuped on me last night on the interstate and threw a CEL and a P1494. I'm leaning towards a coil. Suggestions... It also did it with the old tranny and the new jasper.
 
How's the wiring harness look? Any chance there's some intermittent connections somewhere?
