Greetings,
   I am experiencing an intermittent problem with my truck this last few
months.  I have dual tanks, and primarily run off the "front" tank.  a few
times the engine has just shut off and I've had to pull over to the side of
the road and make a decision on weather to call a tow truck or wait to see
if it starts after a few minutes.  After the first call to the tow truck the
darn thing started right up.  The next few times I just waited for about 15
minutes and she started up again.  I first suspected the ignition relay,
maybe over heating and failing.  I carried a can of compressed air to use
when it stalled again.  I did this and it made no difference.  I have a
friend who is a mechanic who suggested that the front tank fuel pump might
be failing and the fuel pressure drops below spec and the injectors shut
down (possible).  So my next move was to run off the read tank for a while.
And of course nothing has happened yet.  I did do a short camping trip and
had my 3500lb camper on.  I "felt" that I may have lost some power, running
off the front tank on the trip.  But I was just going on feel, it sputtered
a couple of time on the trip, but didn't actually stall.  Anybody out there
heard of this type of issue.  Any ideas are welcome.  Thanks in advance.
