03 Denali Shuts off

[CADDY980]

I have an 03 denali xl. While pulling my camper the yukon shut off while drifting to a stop light. It will turn over and fire then immediately shut off. Before I go spending money on parts, has anyone had this issue? Where do I start?


Thanks

Is your check engine light on?

How many miles on it? First thing I'd check is fuel pressure.
