Trouble code questions

Hey guys, old smokey is giving me some problems lately. after it
has been sitting a few hours and I start it up, the off light on the
gearshift starts flashing. After 5-10 miles, at cruising speed it quits
until I accelerate slightly and comes back on. Then after another 5-10
miles, it goes away and stays off until it has sat for a few hours. When
I pull the code while it's flashing, it reads: P1748 no description in database/
search internet.
Does anybody know what this code is or means? Oh yeah, one more thing,
when the light is flashing, the line pressure reading is all over the place. But
when the light is off, the line pressure is steady.
