Engine hesitation and Stall on acceleration

if it coughs and dies after a few minutes of idling, its running out of fuel or air (flooding). Id suspect crap in the seats. let it die and check your pump shot. If its there for 2-3 cycles your flooded, if its not your empty. Carefully watch the boosters while running and it chokes itself (be very careful of a backfire or fuel blowback) I bet there is fuel visibly pulling out the boosters. IIRC if it runs out of fuel, it will chug and recover, pick up to a high idle for about 2-3 seconds then die. If it is flooding it will just die with nothing on the tail end. Accelerator pump is not in play when its just idling and dying and a low fuel level will make the pump shot small to none. Vegas long shot on ignition issues.
