98 grand caravan 3.3 ltr flex fuel. NEW cmp ckp sensors (just in case) Runs perfect on initial start up. Always between 28 and 36 mins later engine dies. No difference if you are driving or in park at idle. My scan tool pulls a intermittent loss of cmp /ckp dtc. However looking back over the sensor history graphs in my scanner I see no such loss of signal. Motor will not restart until the next day. ALL wiring from both senors have been visually inspected and ohm meter tested from pcm to sensors passes all jiggle tests and water too. I AM STUMPED for the first time in all my days. YES fuel pressure and compression have been tested before during and after failure. Motor has EVERYTHING it needs to run I.E. Fuel injectors fire, coil fires at correct time(9 degs btc on start up), Also I checked ALL components for proper grounding ( trans-axle too!).I thought perhaps I was loosing ground but Unless there is something I have missed but god I have been from start to finish 5 or 6 times now. HELP. Thanks in advance! Matt
