I would recommend that you check to see if you are getting spark from the coil/coil packs. If this is not the issue, then you may be looking at a timing problem.

Mike fuel filter may be dirty and plugging after running tank so low or possibly fuel pump has now weakened and is failing. Have vehicle scanned o see if diagnostic codes are stored to help diagnose.
Does it crank? Or there's no crank no start? If it cranks safely get under the vehicle and bang on the fuel tank while someone holds the key in the crank position with the vehicle in park. If it starts it is most likely the fuel pump.
The crank sensor will sometimes fail when the car gets hot. I have ran some of these cars before until they cut off. I sprayed come water on the crank sensor and the car restarted. Replaced crank sensor and the car did not come back again for that problem again.
had same problem with 2000 dodge ram. would run great then start to buck then die.let sit would start then same thing. it took some time for the crank shaft position sensor code to pop up. changed sensor (very easy) good ever since.
Hi,trottle position sensor ( tps )is a very accurate diagnostic,if this dosnt fix it run a fuel presure test for a posible defective fuel pump,. good luck......
Hi, these are classic signs of a slipped timing belt/chain. :o(
