I have to agree with this. Buy a "dynamic spark tester" at the auto parts store (under 10 bucks), plug it onto the spark plug and into the cap. Run the car and when it starts to fail, put it into nuetral and see if you've lost spark. If so...bad "TCI/ or coil" if you want to call it that. Good luck

I was thinking that the line in the tank is about 3 in off the bottom & the gas might tip towards the back & suck air for a second when going up hill

sounds like there might be a couple things at play here;; if your filter is level with the top of the tank it will drain back in when the engine is off, that's ok,, mine is. the other thing is ; there is a line coming from the fuel pump that goes to the engine, just buy the cap you put oil in at;; that's the vacuum line that runs the pump,, if its plugged, or leaks,, the pump wont work right,, take it off at the pump and blow;;;;;;;; ,, it should be free;; good luck oh,, the gas line should be real close to bottom, mine is touching on the bottom, in the middle of tank, cut at an angle.

my fuel pick is at the front of the tank about 3" off the bottom. hard to drive & see what is going on when on a 25* hill

if that's the case, its easy to take out the hose and replace with a longer one, have it just touch the bottom, with it cut at an angle, if you don't have a longer piece, you could insert a plastic tube in it then adjust; but if you have half a tank you should never have a problem even with it that high,, good luck.
