Hi, my name is***** will be assisting you.

Can you provide the model and type number from your engine so that I can better assist you?

Normally Briggs recommends SAE30 oil in all of their engines unless it is cold winter time weather. This could be affecting the operation of the oil sensor and oil pressure. I would also wonder if the oil pump is operating properly since you say it has a loss of oil pressure. If you will provide the model and type I will work with you to find the problem.
