Could be a faulty fuel pump, they are notorious for acting unpredictibly when they start to go bad. My bet is in a week it won't start at all. Try banging on the fuel tank the next time it won't start, if that fixes it it is prbably a fuel pump.
Running you fuel pump until its at E is hard/bad on your fuel pump since gasoline is the fuel pumps lubrication.

The issue of hot no start is often the crank shaft position sensor, do you have any trouble codes, if you want a free test Kragen auto will do it for you. Let me know what comes up if anything.

Definitely not the fuel pump. A fuel pump will either work, or it wont. It could be a fuel filter, though unlikely, again if it was clogged there would be nothing. Could be spark plugs/wires, a faulty coil pack, Could also be a handful of sensors (o2, MAF, are a few that come to mind). Does it have a manual transmission? If so can the car be started without engaging the clutch (in neutral)? If so check the 2 clutch sensors attached to the clutch pedal.
Probably a sensor. Go to Advanced Auto parts and have them pull the code. Then google it. Or check out Forums.vwvortex.com

Most likely there is a hole in the air tube. Open the hood and check the rubber tube on top of the engine. If there is a rip, just cover it with some heavy duty tape and it will help on a tempory basis.

Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.

Testimonial: "Thank You for your response. The huming sound is present on idle from start-up,tires have just been replaced, would fuel pump be suspect?"
