Add ground beef and cook until beef has browned for about 8 minutes.
Stir in taco seasoning.
Drag set aside.
Using a food processor, place Cheetos in, and pulse on high until Cheetos are blitzed to a powder.
Heat tortillas in the microwave one at a time for 20 seconds.
Brush melted butter on both sides and dust with Cheeto powder.
Heat nacho cheese in the microwave for 1 minute.
Working with 1 tortilla at a time, place ground beef in the center. Top with nacho cheese and tostada shell. Spread sour cream on top, then top with lettuce, tomatoes, and cheese.
Repeat with remaining tortillas.
Fold the edges up over the center, folding inward as you go (like dog-earring a page in a book).
Use a small plate to hold edges in place while you work with the remaining tortillas.
Heat olive oil in a large skillet.
Place wrap seam-side down and cook until the underside is toasty-about 4 minutes.
Flip with a spatula and cook another side about 2 minutes longer thus Flamin' Hot Cheetos Crunchwrap is ready.
