If my '85 Digijet stalls after the first initial start, it sometimes will
crank much slower and is difficult to re-start.  It cranks along time, (I
have two Group 41 batteries), but slower than the initial cranking speed.
What would cause it to crank fast and start, but then crank slower the
second time?  It cranks faster with the pedal to the floor and does
eventually start with the pedal down.  It seems like it is working harder
to crank on the re-start, like more compression.  Maybe the valves have
pumped up a little from the first minute or two of running before it
stalled?  Is there anything electrical I should check?  The starter is new
and the batteries (two Interstate 41's) were purchased last summer.  It has
done this on several occasions.  It has never not started, but has come
very close a few times.
