Sounds like the starter may be getting heat soaked. Especially
possible considering it's RIGHT next to the exhaust. I hear it's not
fun to replace the starter in these trucks. I'm expecting that to be
my next repair, after the fuel pump last week and alternator this
week. I have a 94 Jimmy....
Check your connections first but more than likely the starters bad. I
changed several in my '89 as the rebuilts suck. At least the lifetime Napa
ones lasted a little longer. It's in a tight spot and wires to it have to
be accessed from underneath and through the wheel well.
It's a tight fit coming out between the exhaust pipe & frame, so tight that
it will pass through in only one "magical" spot but it will come out. At
least that's how it was on my '89 4x4.

Thanks to all who responded. I did have to change the starter and it was
just like repairman says below except I also had transmission coolant lines
to deal with. The standard size starter will not fit this truck since only
the smaller more expensive one fits.
