I was driving westbound on I-10 approx 1 mile east of Hwy 60 (in Beaumont) when my truck suddenly felt like it bogged out and braked simultaneously. Thought it must be an electronic issue- maybe Eco shut down too many cylinders. But on my way home about 8 hours later the same thing happened in the exact same spot- only I was in the eastbound lanes this time. No other issues with vehicle prior to this incident or since.
