Check the oil pressure. Rent or borrow an oil pressure gauge from a parts store such as Advanced, O'Reilly's, Pep Boys, etc. Use another vehicle to get there and back. Remove the oil pressure switch (see image) and replace it with the oil pressure gauge. The gauge should read at least 20-30 PSI with the engine running. If not, the oil pump is failing.
