difficult to start, cuts off while driving. Any suggestions are welcome. My mechanic is baffled.

Fuel pump/filter, fuel pressure regulator, vacuum lines. Have good gas in it? Clean MAF sensor.

Oil in coolant? Coolant in oil? Catalytic converter clogged?

Take a look at the plugs know when they were changed last? Did the wires going to your spark plugs look old and cracked? Do you know anything about the coils being changed or spark plugs or wires? Is the engine air filter completely clogged up?

Thank you for that information. I have relayed this to my mechanic. He may have found something blocking the computer probe. I will get back to you with some issues he has found. Solutions are good to share. thanks
