runs hot,ok, restarts hot ok
just dont start , cold, but it must because how do you get to 2hours?
my guess, is it sometimes does start cold.
ever tune it up at the critical 60k mile service, ever, this decade?
that covers 99% bad cold starts. so , we do that first.
diagnosis is like 10x a tune up, so........ $$$$$
check harmonic balancer for slop back and forth,,,,these 3.8's have a crank posision sensor behind the balancer,that run off of the balancer,,,gthe rubber wears out and they start to flop around and timing gets messed up.../they cost around 100 bucks for a aftermarket,and if thats the problem,do yourself a favor and replace CPS while tour at it....good luck...Lee
