I had the same problem with mine. I had to have the spider injectors changed. cost alot but it fixed the proble. but my advice once that is fixed something else will go wrong. I think I am going to get rid of mine.

This sounds familiar to me. I assume you replaced the fuel filter, if not, do so. Anyway, the same thing happened to be and I made it to the garage somehow and they said it was the pump, located inside the tank. 3 days later I picked it up and paid $350.00. It happened again a month later and I had it towed home ( the service garage changed hands and would not honor warranty). I unbolted and unstrapped the gas tank with a jack under it. The gauge said 1/4 tank so I figured on 40 lbs of fuel plus the tank.....wrong.... The tank was empty and the fuel pump had never been replaced. I has just never run my tank down that low before, so I had no way of knowing the gauge/float was miscalibrated. You never know....
If all OK then motor probably got some **** on the brush gear get sombody to help you, firmly apply hand brake.... ENSHURE IS IN NUTRAL OR PARK!
while they hold kek in crank position tap the starter motor with a hammer to free the crrap... that shuld do it!
The fuel filter is only about 5 bucks worth of work/material. Most of the time you have to get 3/8 fuel line and clamps and a filter with male adapters and just cut out the old one. But it's still a 20 minute job. Also try some dry gas or fuel treatment. If you change it and it's still acting up I think a Vacuum leak or a weak coil is the culprit. Hope this helps.
If your getting gas and spark get an obd 2 scan tool and check your mass air flow sensor. I had the same problem. If your having a problem with this vehicle always check the computer first; it will save you tons of headaches later.
replace fuse and relay.also check oil pressure switch.it controls fuel pump also. check fuel pump wires and fuel injector fuse .if all is good pcm could be faulty it controls fuel pump on .command circuit
