My 1990 90 quattro 20v has been my daily driver for about 10 months. I usually drive it about 26 miles to work (13 miles each way) and haven't had any problems before. But the other day I drove it 100 miles (50 each way) and right before I got home it died. I tried to start it back up and it just cranked. After I got it home I started it in the driveway and let it idle and it died after a few minutes. This morning I drove it to work like normal and didn't have any problems. Any ideas what the problem might be? I pulled the codes and there was nothing.

When I first got the car I did a basic tune up and some other misc things. This is the work that I have done on the car. Plugs, Wires, Cap, Rotor, O2 Sensor, Fuel Pump, Fuel Filter, Knock Sensors, Timing Belt, 034 Injectors

Thanks in advance for any help.

Fuel pump still priming when the key is turned to the on position? Gas in the tank? One of crank sensors or the hall sender.

I had a similar issue when my MAF went bad. I don't know if that helps, because mine is a Buick, but if the MAF freaks out when hot (as mine did), then it won't read proper values, and the result is no fuel into the motor.

HTH,
Eric

i have not known hall senders to cause car to stall, you can unplug them once it running and it doesnt care. they will prevent it from restarting though. I vote crank sensor.

I tested the hall sender with a LED test light and it looks like it's working properly.
I retested the crank sensors when the engine was hot and I got readings of about 1200 ohms which seems pretty high if it should be at 1000 ohms. I think I will try replacing those.
