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.

Question2:
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.
