Oil gauge dropped to zero

Question 1:
Does anyone know what might cause an oil pressure gauge on my '95 E420 to drop momentarily to 0 while driving during cold outside temp then goes back up to 3. I checked the oil level and was fine and was changed recently. I am suspecting the oil pressure sending unit. any ideas? This only happened once while it was cold outside. No malfunction light came on.

Is it easy to replace the oil pressure sending unit?

Question 3:
If anyone has specific instructions on how to change the oil pressure sending unit on a 95 w 124.034 (E420) would appreciate an e-mail or something.
