this problem may be the crank sensor,,these may do this when they first start going bad and not give a code
Under hood, passenger side, lower engine area, front of crankshaft pulley, mounted in engine block
if it is oily,the problem may be a leaking front main seal and is getting on the crank sensor...a mechanic may charge you 3hrs labor..depending on what the mechanic in your area charges per hour
this problem sounds as if the crank sensor is failing
