i recently acquired a 93 lx, it has a stumble when it gets warmed up and i get on it but today it stumbled and the fuel pump sounded like it went dry for a second then picked up fuel again, it did this 3 times then just died as i was driving started right up and 1 mile down the road did it again. could this be from fuel over heating temp gauge read 220 degrees. car is a 408w, full manual c4, 3800 stall, 4150 holley 750, 4.10 gears timing 30 degrees at 2500 rpm
