Use a fuel pressure gage, check for proper fuel pressure, key on engine off. Then with key off, see if pressure will hold for a bit? If the pressure drops like a rock, check for a fuel pressure leak, check for fuel injector leak and fuel pressure regulator leak. If fuel pressure regulator is connected to fuel rail and has a vacuum line, check to see if gas in the vacuum line, if so, pressure regulator is faulty.
Check for applicable trouble codes? How long since a tune-up?

i gaurantee that it is the fuel pump ressistor up on the passenger side front behind head lamp assembly you will find the connector with two wires going to it. no need to remove old one install new one and connect wires to new one leave old in. dealer only part but not expensive. dont belive dealer when they try to talk you out of it. This is a kit to relocate a ressistor that has been installed in a poor location. I promise this will fix it. My wifes car did the same thing, took 20 minutes to fix and that is only because i am an electrician and am finicky about where to locate wires etc. the kit comes with installation instructions however they are a little vague. trust me. easy fix. my dealer tried to get me to leave car for repair and said it sounds like the theft detterent system. they were wrong and i was right. dont trust em

the owner probably rerouted the fuel line because like my 92 chrysler lebaron v6 3.0 the fuel lines keep seeming to come off and the clamps always break. I have replaced the clamps 5 times in a month and replaced filters 2 times in 2 months. The only thing i could think of is that your fuel is being cut off possibly because there is no filter to clean all the junk out. Try putting a fuel filter on and see if that will work

it might be a blockage in your fuel lines, this will sometimes make your car go into failsafe, because it knows there is gas in the car but a limited amount reaches the carbarettor, this is also why it will sometimes stop while trying to "rapidly" accelarate ( from a red light )
