CAR STALLS, SOMETIMES WON'T START AT ALL, WHEN IT DOES RUNS FOR A FEW MINUTES ACTS LIKE NO GAS

1999 Volvo S70 • 121,000 miles

I really need some help here. Been told that it could be the throttle body and number of other things. The ETS light went on and off for the past year and just recently the car stalled and started right back up. This lasted for a couple of days, now the car will start and shut right back off. Can't keep it running very long at all and acts like there is no fuel. Won't rev the motor even if you push the gas pedal when you do get it to start.

The first things to do are to get the trouble codes pulled and translated. Any Advance Auto or Auto Zone will do this for free. The next thing would be to test the fuel pressure. Both aforementioned stores will loan you a test tool for this. Next would be to consider taking the throttle boday and IACV, Idle Air Control Valve, off and clean ports on intake manifold and in throttle body with carb cleaner. Also, replace fuel filter if applicable. I think the filter is in the tank on your car.
To go through this in better detail I am giving you a diagnsotic walk though which will cover all of these points in detail and go through them in a logical "Process of Elmination" so you don't end up spending unecassary money fixing it.
Just use the link below to get to the diagnostic and follow instructions with information I gave yuou to get help with code readings, etc. I am actually giving you 2 of them.

I have taken it to Advance and pulled the codes, replaced O2 sensor and MAF. There is no codes this time. ETS light was coming on randomly and would go out, there is no check engine, no ETS nothing. Now the car will not start at all. I was told that the turbo requires higher octane gas and have ran that for the past year I owned the car. Checked with Volvo and the throttle body was not replaced on the extended warranty, could this be the issue?

If it is a turbo and there was a recall on the throttle body, not sure why you mention it under extended warranty, it could be the poerts need cleaning or the throttle position sensor is bad. However, if it is not starting at alll I would look at the fuel pump relay and check the fuel pressure.
