Service Engine light comes on and then blinks when ascending a slope/hill
How long since you've checked your oil?
About 7 months ago I went to have it changed; but I got a funny feeling that they did not do anything. When I first got there they said it would take a while. I went to the bathroom and came back and they were like "your car is ready." But anyway - could that be the problem?
Also its wise that you check your air filter and if there is a slight stall do check your inline gas filter. Its located beneath the vehicle near the pass. side door. Good Luck SEMPER FI
