Good morning. I have a 1997 yukon with 114000 miles. i recently moved and was hauling some stuff nothing to heavy but on a hill it felt like the truck was sputtering/ stalling it drives well on regular highway and street driving only does it while climbing.. anybody have suggestions as to what it might be its not giving me a service engine light and was tuned up around 1 year ago with all ac delco parts including fuel filter. Any help would be great

Did it sputter at all before your tune up?
Its been running great after the tune up been on a few long road trips with out any problems. This just happened earlier this month ive also noticed after being parked and putting the truck in reverse it does a very slight sputter and again when i put it in drive but other than that it drives great.
Fuel pressure or check for clogged/high back pressure at the cat(s).

Fuel pressure spec is 60-66 psi with ignition on/engine off.
The stumbling uphill (increased engine load) was something mine did when I had a damaged converter. Here is GM’s procedure for checking for an exhaust restriction. In lieu of the specific tool that they mention, you could probably rig one together fairly easily.

+1 for the suggestion to check your fuel pressure and for exhaust restriction.
Did your tune-up include new cap and rotor?
