Motor dies

Spud,
we took the dragster out today for some shake down runs. we changed lots of things based on your great calculator thanks, it helped alot! But  after a semi hard burn out the motor quit  reprimed it, fired right back up did a great pass but at the end of the track it died again.

we have two vents, one in the  front and one in the back, on the top
7 gal tank with the pickup on the bottom, 1 inch tube, about 8 inch long, with the bottom scalloped
we think the fuel might be sloshing around in the tank uncovering the back of the pick up tube the scalloped part.
our plan before the next test was to put a trap door in side the tank
   
we would like your thoughts !

is there is something stupid we are missing or over looking
 
YES the tank was full of fuel !!  ;D

we made 3 passes on this motor last year before the cam went south and it did the same thing
so we still have the same issues or some thing still wrong
thanks for your time

 ps is it vacation time yet ?

Paul New:
Is there baffles in the tank?

Paul New:
Did you get on the brakes hard after the burnout

BK:
If tank is long and narrow try extending the pickup into the tank about a third of the way. You should be able to do it without cutting tank up.

hotrod316:
no baffles in the tank, the pick up is about 8 inches into the tank, will ask the driver about the brakes
thanks
steve
