1977 F250 stalling problem
 

My truck 1977 Ford F250stallswhile I'mdriving
down the road. I shift to nuetral and try starting while rolling.
Starts every time. Does this 2-3 times first 10-15 miles out...then no more. Drives all over rest of day with no trouble.
'CarTalk' guys said something about the "igniter?"...what the heck is that?
