2012 Patriot. Yesterday I was driving back to work from my lunch break and my car felt slower and then shut off in the turning lane. It cranked but wouldn’t start. I got it towed home. Hours later when I got home, I started it and it cut right on.
Fast forward to today. I drove my car about eight miles with no issues. I then left to go pick up groceries later in the day. It cut off in the pickup spot. Went inside and bought starting fluid, made it about a quarter of a mile before it cut off again. Tried starting fluid again and it wouldn’t turn over and I felt the vehicle shaking. Thought maybe it’s a fuel pump issue and was just trying to make it home. Hit the fuel pump and the car drove for another half mile before cutting completely off. Waiting on a tow now. Any ideas?
 
Is it cranking? If it'll crank but not start, it's probably something with fuel delivery. If it's not even trying to crank, it could be something else.
 
Any ideas?
If possible, get the codes read and see if there's anything that might help narrow it down.

Crankshaft position sensors can intermittently fail and cause random stalling and hard starting, though they don't always set a code.

Another source of no start problems can be corrosion on the wiring and pins of the relays in the relay box down by the drivers side headlight.
 
If it were a fuel problem, it should have at least tried to start on the starting fluid. If it didn't I'd go more towards an electrical issue.

So I replaced the crankshaft sensor. The car wouldn’t shut off again after I put the first one I bought in there, drive for approx 1.5 miles and then shut off. Took it back and bought a NTK one. That one worked. I drove the car for approx 15 miles after replacing it, including on the interstate. I am still a little nervous. Does that sound like it was likely the issue?
