Check your fuel pump relay. if not that, then it's your fuel pump. the gas gauge is in the fuel pump, so if your fuel pump stopped working, your gas gauge won't work

check the fuel pump fuse/relay, could be just bad enough to cause an intermittent start/no start. and check fuel pressure,spark and the crank position sensor.

Try resetting the asd "auto shut down fuse had a similar problem the jeep would crank but did not get spark or gas also check your fuel pump? and the asd relay may be bad it will prevent the jeep from getting no spark and will not fire some jeeps have security problems

You do have a filter and it's mounted right on top of the pump on outside of tank...it is also the pressure regulator. You really should put a pressure gauge on the fuel system and check it out though. you may find there is a problem elsewhere. Good and proper testing is the only way to get answers about problems especially now that systems are all electronically controlled.

There could be two problems here:
1. That buoy floating tank is not working properly
2. That the electrical system that fails to submit the dashboard.
