Problem not occurring when at mechanics but usually won't start, dies and more

What is your question?

Started with occasional dying, then occasional no start .. full tank but now gauge rests on empty. Security light flashes, abs break and low gas light comes on occasionally with no start. Third time Mechanic said it's fine only to have symptoms return almost immediately. Have put in New fuel pump and map sensor, and battery cables. Different results each time I attempt to start the truck including no bus in odometer space, check engine, gas and security lights... sometimes it starts then dies. Sometimes runs great for days.. This is an 01 durango 5.9 L ..
