keeps cutting off
have 82 f150 300 auto with dual tanks that has got me stumped
the motor will shut off driveing down road and to get it running again i switch the gas tank selector and it starts running again. the catch is i bypassed the front tank when this started happening because i thought it was the front tank causeing the problem so the switch isnt really switching anything but the gas gauge
when this first started happening i would turn off ignition switch and turn back on creating a backfire that has ruined my new muffler and blew out the donut gasket on exhaust manifold
this leads me to think its tank related but i cant figure why switching selector would cause it to run again
i am going to run a wire off coil neg to a light bulb in cab to deternine if i am loseing spark and if light keeps blinking it would have to be fuel related, right
anyone with ideas i sure would appreciate them all
thanks

You are on the right track as far as doing some testing.
