When it stalls are you loosing spark?
When it stalls if you remove the spark plug wire and jump it to ground does it spark? Have you replaced the crankshaft sensor yet?
You are very welcome!!!
You will need to check the codes in the PCM first and repair any codes, then check for spark, if none then see if coil is getting 12v constant, and a ground pulse on the other wire.. If so then your coil is bad..
Let me know if you need anymore assistance,
