1989 Mercedes 190E 2.6......Fuel Pumps running fine and suddenly die.

[ashevillemerc]

Just purchased this car from a man, it had been sitting awhile, It needs some TLC but the problem I am having with it is that the car will run for approx 30 sec. Then just die. I first looked at the fuel pump relay crossed it so it runs all the time and the issue is still there. I had a buddy start the car for me and I got under it at the fuel pumps with a test light, after the car runs its approx 30 sec all my voltage at the fuel pumps drops and I have no juice at the pumps. The strange thing is that once the car dies, it will start right back up and run again for around 30 sec. It starts right back everytime and everytime after that 30 sec period I again and again lose all power to my fuel pumps. All while my fuel pump relay has been crossed. What other parts should I look at that could be the culprit in my fuel pumps loosing their juice.
