Answer 1

P1391 Intermittent loss of CKP or CMP

What happens when this code is set, the PCM does not see either the CMP or the CKP, If the engine stall it does not see the CKP, when there is no CKP there is no ignition or fuel pump operation, The CMP loss it does not synchronize the fuel injectors, If this code set with a CMP code then you replace the CMP these are Hall -effects sensor they do where out, If this code set with a CKP you replace the CKP sensor, If it set by itself , You need a PCM , other than that you just unexpectedly stall out.
