Hello!
Newbie here and hoping for some advice: My 1998 GMC T-7500 Bucket Truck with a CAT Diesel and Allison Tranny with 130K miles normally runs great, EXCEPT when I shut it off on an incline (nose up) of even the slightest, won't start back up. Tank is anywhere between 3/4 and full, makes no difference, Have to ether it to start it, then is stumbles until I get it leveled out. Even driving up steep hills I can feel it stumbling a bit. Any suggestions on the issue? Tank strainer or a pickup issue? Weak in-tank fuel pump? Gets annoying when up in the bucket and have to use rescue mode to descend. Thanks!

I believe it's the 3126 but I will double check when I get back to my garage
