06 BRM jetta tdi crank no start.

My Jetta Brm has started a couple weeks ago the fans ran about 5 minutes after shutting off the car and never cut the power so I unplugged them as it has been around 20 degrees and I don’t drive much farther then the 10 miles I go to work so and the car doesn’t even run over 180 anyway. Then recently it had died on me and then next morning after leaving on the side of the road it started and drove home the next morning. Then let it sit for about 2 days went to drive it the next town over and got about 6 miles away from my house and it died. Then had crank no start. Let it set for about 2 hours then went and got it about half way home then would not run for more then 10 to 30 seconds so it got towed home. My car also has the normal warning lights on the dash but the car is off and isn’t on. Relay plug 458 also buzzes when the car won’t start. But when it stops the car will start temporarily then when it dies it buzzes again. Tried switching them out and it did the same thing on the same plug no matter what. Also when buzzing no fuel is being pumped through the lines but when it is not buzzing fuel flows as it should. At a complete loss on this and have no clue. Any ideas would be helpful!
