looking at buying this 96 doge neon today. its a five speed. has had a new fuel pump, plugs, wires, mat sensor, coil, and O2 sensor. but after it runs for a half hour it starts to die. takes a minute to start back up and then only wants to go a few more miles before it does the same thing again. it doesnt get hot so i dont think a head gasket. any ideas? what should i look for? thanks adam

 

is the check engine light on...

 

no cel is not on. any censors that could cause this?
