Car won't start randomly. Usually on short drives after I park but it could happen at any given time. Happened a few times while driving or at a stop light to. This is insane as Ive forked out so much money already, (not for this specific issue) what is life? its a 2000 Passat 1.8t ATW. One time I was going about 90 and my car lost power, epc light and battery light came on as I started to pull to the side of the road it regained power and I got back up to speed. Im not having any electrical problems with windows or lights, only thing I notice is when I roll windows up to the top and keep trying to roll them up, as I pull up on the buttons, the car idle jumps a lil bit... but Im pretty sure its always done that. Well the light inside the trunk doesn't work and the "boot lid open" indication on dash don't ever show up but I haven't been able to link that to the car not starting, cranks all it wants, just won't turn over. Any ideas? Alternator checked and good, timing belt recently done, battery should be good, MAF replaced with BOSCH, Premium gas always used, driver door lock module replaced... Sometimes I get it to start by undoing the battery terminals for a while but not always a solution.

Crank position sensor also called ESS (engine speed sensor) .... just replaced mine. Car would crank but not start, EPC light, high idle (1100 rpms).
