In a large saucepan, heat the olive oil. Add the garlic, pancetta and crushed red pepper and cook over moderate heat, stirring occasionally, until the garlic is golden, about 5 minutes. Add the tomato paste and cook, stirring, for 1 minute. Add the canned tomatoes, crushing them with the back of a spoon; season with salt and pepper. Stir in the sugar and basil and bring to a boil. Reduce the heat to low and simmer, stirring occasionally, until the sauce is thickened and reduced to 3 cups, about 30 minutes. Discard the basil and garlic.
Meanwhile, in a large pot of boiling salted water, cook the spaghetti until al dente; drain. Toss the spaghetti with the hot sauce and serve.
The sauce can be refrigerated for up to 3 days or frozen for up to 1 month.
